I am using Chrome to debug an app. Usualy I get a complete stacktrace when profiling my app.
But recently the stack just disappeared. It only shows the layering, drawing and native events, but no longer the JavaScript executions.
In the settings I have uncheckt the "Disable JavaScript samples" and tested all other preferences regarding the performance tab. Nothing helped.
Other sites (like stackoverflow) won't work eighther. Chromium has the same problem.
I am running this on Ubuntu 18.04.4 LTS.
Anyone else has a clue how to fix this?
I'm affected by this as well. I filed an issue at https://bugs.chromium.org/p/chromium/issues/detail?id=1071961. Perhaps you could add more detail so the Chrome team can fix it faster.
Are you using an Intel CPU or an AMD one? I'm using one of the latest AMD Threadrippers. Wondering if that may be the cause.
I'm attempting to run intellij from a Linux machine that is connected with putty that has had the display forwarded by Xming. Intellij is able to come up and I'm able to use most of the widgets, however I'm unable to select or type into any of the text fields.
I've found the following bug report: https://bugs.openjdk.java.net/browse/JDK-8040662 however, since this is not a common use-case, the bug is sitting at "won't fix."
I also keep finding similar questions, such as: X11 forwarding affects Java Swing GUI dropdowns - Items not selectable, Menus collapse immediately but it seems like nobody has an answer.
Currently I'm running with the following versions:
Intelij: IC-141.1532.4
Openjdk: 1.7.0_76
XMing: 6.9.0.31
The solution is to use the current Oracle Java 7 JDK, which has been patched to fix this issue.
Now that TideSDK is effectively dead, I've been looking into alternative 'wrappers' to run HTML/CSS/JS applications as stand-alone desktop applications. The three viable options I have run across so far, are NW.js (formerly node-webkit), brackets-shell, and Electron (formerly atom-shell).
The problem is that there does not appear to be a sufficiently complete comparison between the three in terms of feature set, compatibility, etc. I'm hoping to turn this into a more-or-less canonical thread on the (objective) differences between the three, in particular regarding:
Platform support; operating systems, dependencies, etc.
Language feature support, as far as HTML5, CSS3 and JavaScript are concerned. Think things like "does HTML5 video work, and if yes, what codecs are available?"
Non-standard extra features, such as tray icons, popup notifications, and OS-rendered menu bars.
Extensibility; eg. ability to 'plug in' native code, talk to Node.js, and so on.
Architecture; in particular the architectural differences that affect daily usage as a developer.
Debugging; included development tools, compatibility with commonly used tools like node-inspector, etc.
... and so on.
What are the objective, technical differences that matter when making a choice between them as an application developer?
I did similar research about two months ago, and in the end I went with node-webkit. The biggest upside on node-webkit is node.js and npm. The package management of npm is really nice, and node has well done filesystem access.
Brackets-shell looked interesting, but other than a nice IDE I didn't really get what made this one as good or better than the rest. They are very clear that "The brackets-shell is only maintained for use by the Brackets project ", that screams run away to me.

Atom-shell seems to be recently active, but it seems much like brackets in that they are really writing and editor/IDE that just happens to be attached to a webkit runtime. It also is built on top of node.js. This one has the downside of being difficult to search for stuff online without being reminded of your middle school chemistry.
I really don't want an new editor, and most programmers have their favorite already. For the actual application development, they pretty much work the same, and should, since they all use webkit. You basically write 90-95% of it like a website, and then deal with the native parts, and some config.
These things are true for all three of them
platforms - runs on Windows, Mac, and Linux
language support - HTML5, CSS3 and Javascript : since they run javascript you can download and run nearly any library/framework that you want.
The big caveat on webkit is codec support. Typically you will have problems with non-free video codecs, unless you rebuild the dll/so to support them. For example the shipped node-webkit won't play mp4 video.
I've been playing with Atom-Shell over the last few days, and I am loving it so far.
The best part about it is that it's backed by GitHub.. which should allow you to settle into the platform for the long term, especially if it gains a large following. It's also made possible by direct Node.js improvements courtesy of a contract with StrongLoop, who is a major Node.js contributor (they claim to employ more Node.js core developers than any other company, even Joyent).
I've also found it rather comfortable to get started. It took me about a day to learn the structure and get my first proof of concept running. Very cool.
Bullet Points:
Platform support: Windows, Linux, Mac OSX (More Info Here)
Language feature support: HTML5, CSS3, JS via Chromium - so far, zero issues, but I have not tested video specifically.
Native Features: Native App Menus, Task Tray Support, Global Hotkeys, Protocol Handler Support (that I've seen so far)
Extensibility: Excellent Node.js integration, both the client and server can "require" Node.js modules and natives. I've also successfully tested Bower libraries (incl jQuery) without issue.
Architecture: Covered in the other points, but in general its very smooth.
Update (11/25/14): I've not yet found use case for Atom-Shell in any official capacity, but I have used it to build a few small apps for my own use, the most complex being an app that pulls my time logs from my PM software and creates Paypal invoices.
My opinion of the platform remains positive. It's pretty awesome.
On my time invoicing app I successfully brought in Bootstrap 3's Dashboard Example Template and a few node modules (bluebird, Paypal SDK, Teamwork PM Client) to create a mildly complex app. It took me a few days and does its job well.
I really cannot think of anything negative to say about Atom-Shell, its solid, stable, fast, and easy to code for. I hope this helps someone.
Besides fully support Web standards, NW.js supports a list of non-standard features for native app development including:
Protect JS source code by compiling them into machine code: https://github.com/nwjs/nw.js/wiki/Protect-JavaScript-source-code-with-v8-snapshot
Jailed devtools: https://github.com/nwjs/nw.js/wiki/Devtools-jail-feature
Additional security model with which you can do more in DOM: https://github.com/nwjs/nw.js/wiki/Security https://github.com/nwjs/nw.js/wiki/Changes-to-DOM
enhanced file dialog: https://github.com/nwjs/nw.js/wiki/File-dialogs
kiosk mode: https://github.com/nwjs/nw.js/wiki/The-Kiosk-mode
supports for a growing list of chrome.* API, include chrome.webRequest so you can intercept HTTP requests from DOM: https://github.com/nwjs/nw.js/issues/518
support for rich notifications, print preview, many more chrome.* APIs, Chrome Apps and other Chromium features starting from 0.13.0-alpha0
There is much more to see in the wiki including Menu, Tray, etc.
I've been working with brackets-shell for some time now, here are some of my findings:
brackets-shell is primarily developed as a shell under the brackets IDE project, but the project can run any web application. You just need to point it to your own html page. Clint Berry wrote an excellent tutorial about doing just this: http://clintberry.com/2013/html5-desktop-apps-with-brackets-shell/
The project is backed by Adobe and has a lot of activity
Documentation could be better
platform support They support Windows, Mac and Linux. An installer package can also be created. I only tested it on Win and Mac, it works great.
feature support html5, css3, js. Html5 video does not work out of the box, but is very easy to enable (by default the ffmpegsumo.dll is not copied into the installer, if you change the script to copy it it will work).
native features menu bar, 'open file with', file system access. I am not using any of these, as all I need is the communication with the node process.
extensibility a nodejs is built in, and you can communicate with node from your web application. In this way, you can use node to access the filesystem etc.
architecture The project is well set up, keeping a nice separation between the shell project and your own web app running inside it. In your own application, a global appshell object is available which gives you access to the brackets functionality (filesystem access, communication with node process, ...).
One thing to note (if you care), is that the Electron officially does not support Windows Vista. Vista's market share is about halfway between OSX 10.9 and 10.10 (both of which are fully supported by Electron). Vista is also still supported by Microsoft until 2017.
NW.js works fine in Vista, as well as OSX 10.9+. NW.js works on Ubuntu, Debian, Zorin, Manjaro, Arch, and most other Debian based Linux OS's. Electron has refused PR's to fix Ubuntu specific bugs on their platform which is concerning.
NW.js works in XP too. Currently 18% of the market is still on XP. So if you're desktop application is more general purpose or wants to have access to the late adopters still on XP, you're probably better off with NW.js (0.14.7) as Electron only supports Win 7 and up.
If you use NW.js 0.12.3 you can also support OSX 10.6+ and very old versions of Debian based Linux OS's like Ubuntu, and Win XP+. It is recommended that you do special builds just for those legacy systems though and use the newer versions of NW.js for newer OS's.
I've been looking into this for a day or two now. I've found other people who have had similar problems in this thread. According to the "Where to download" section of this minecraft wiki there is a known problem of black screens on 64-bit machines using LWJGL since v2.8.1. I've tried using older versions of LWJGL with no luck; I'd still get the black screen. Does anybody have a solution to get this working on a 64-bit machine?
I know application questions belong on super user but since this is an IDE I thought I might try it here.
For a couple months now, MonoDevelop likes to appear on my second monitor maximized when I start it up. I have to unmaximize it and move it over each time.
I thought it was some weird preference setting I had messed with but I recently install Windows 7 and the first thing I did was get Monodevelop back up and running. It still goes to that second screen.
Anyone know why?
It might be a GTK+ Gdk.Screen issue. AFAIK none of the core MD devs have dual-screen setups - and definitely not on all platforms. Best thing to do would be to file a bug.
