I am working on a mobile website at the moment and I refreshed the page, Chrome quit unexpectedly, and since then all touch screen emulation is absent and/or failing.
Chrome Version: 36.0.1985.125 m,
OS: Windows 7 Ultimate SP1
Google Chrome suddenly and unexpectedly stopped emulating devices properly. All touch screen functionality has been disabled and apparently removed. When I emulate a device, the Sensors box fails to be checked and upon inspection, does not show any 'Emulate Touch Screen' option.
I have tried the following, all in conjunction:
Uninstalling/Reinstalling Chrome and deleting all personal settings, including uninstalling all extensions, restoring all defaults, etc.
Restarting the computer
Running anti-virus software
EDIT: Installed Chrome Canary which produced the exact same problem
Please let me know if there are any other relevant details that I might need to add.
Sorry about this. We overhauled the touch emulation in Chrome 36 to be much more accurate (sharing code with what really happens in Chrome Android): https://plus.sandbox.google.com/+RickByers/posts/CBCmhVttj5C. In the process we ended up disabling touch emulation when real touch support was present (at the time we thought this was no big deal because if you've got a real touchscreen why would you want to fake one with mouse?). But some Windows PCs report that they have a touchscreen when in fact they don't really (Eg. Visual Studio installs a touch screen emulator I believe).
We're fixing this at http://crbug.com/395531 - hopefully there will be a Chrome Canary build soon that re-enables touch emulation in these cases.
In the meantime you can mostly work around the issue by disabling Chrome's support for built-in touchscreens at chrome://flags/#touch-events. Make sure you set this back to 'Enabled' after Chrome is updated to fix the issue. With this disabled, some minor aspects of touch emulation (eg. DOM0 ontouchstart= handlers) will not work properly.
Stop the "Tablet PC Input Service" and restart chrome. If chrome thinks you have a touch screen, it won't let you emulate one.

I've installed the Chrome Virtual Keyboard (like it), but one major issue. The Settings Screen ALWAYS comes up on first startup of the browser. Is there any way to prevent this? The app will be running in kiosk mode, and obviously this isn't a good thing
I'm experiencing black screen in google chrome (and a lot more...read below) after waking windows 10 up from sleep mode.
This issue appears in google chrome and all derived applications, in few words I'm experiencing this in:
Google chrome Version 80.0.3987.149 (pretty sure i was having this issue also before)
The new Microsoft Edge browser based on chromium
All the pwa (progressive web apps) installed with chrome or edge
All electron applications like:
Visual Studio Code
Whatsapp
All the Electron applications made by me.
I had this issue for a long time but the spreading of chrome based services is going to make this thing a lot annoying...
I'm using Windows 10 1909 home 64 bit (pretty sure I was having this issue also in windows 10 1903)
WORKAROUND: if in google chrome (or edge chromium) i keep a tab that in the closing prompts a javascript alert, in the moment when the alert is prompted, the issue is gone, the black screen is gone and i can return to see the whole tabs.
So after waking up windows 10 from sleep mode, if i see black screen in the browser i can just close it with the cross in the top right corner, in that moment the alert is prompted "are you sure to leave this page?", i answer "no i want to stay in this page" and the issue is gone.
Of course this is a workaround cause you can forget to keep that site in the tabs of chrome/edge, and this doesn't resolve the issue in visual studio code.
Starting google-chrome with the --use-gl=desktop seems to work with no side effects.
I had same issue with Fedora, Chrome and NVIDA drivers. At first I tried enbling the vulkan flag.
Go to chrome://flags and enable ignore-gpu-blacklist and enable-vulkan. However, Chrome performance suffers and others have pointed out with this settings.
Found the vulkan tip in a comment here. The use-gl-desktop tip here
I am trying to debug remote Chrome, the device could be connected, and inspect the tab starts fine.
But in the window of remote debug, everything is a mess. the GUI is terrible, which makes the functionality totally unusable, see picture below:
resize this window or change the resolution is not working.
some times tabs like elements, source, networks could presents, but under the source tab, there is search bar keep presents and covers all area of the codes area.
this is totally not working.
OS: Win7.
PC Chrome version: 63.0.3239.108 (Official Build) (64-bit)
I don't think this should related to Mobile Chrome or android version.
Is there any possible reason for this?
I think Chrome is a widely using browser this can't be a formal released bug for Chrome, right?
The checkbox is gone. Did they move it again?
In recent versions you could find "Emulate Touch" in the Emulation->Sensors dev tools area.
Note I am aiming to emulate iPhone 5.
Per this discussion http://t.co/GTK2jzUX4m it appears that there is a bug where Chrome will not give the option "Emulate Touch" if you are on a "device" that it believes is touch-enabled. So, I haven't fully tested this, but my guess is that this version of Chrome doesn't support Emulate Touch in Windows 8 since it supports touch natively, even if your hardware/device does not. Fix is coming, I guess.
I discovered I had a problem when I checked one of my uploaded three.js projects. At first I thought maybe I had done something wrong. My project used r63, so I updated to r65, but that didn't solve the problem, even after clearing the cache and refreshing. I then checked a couple of the demos from the three.js site, and I found they are slow for me, too. As an example, http://carvisualizer.plus360degrees.com/threejs/ autorotates incredibly slowly in Chrome, but at normal speed in Firefox and IE 11. I also tried http://helloracer.com/webgl/ which is fine in Firefox but really choppy in Chrome. It's a disaster in IE11, by the way, but it's an older demo. My project uses OrbitControls, with autorotate enabled. The model is a 16MB JSON file (200,000 triangles), but it worked fine before and works fine in Firefox and IE11. I'm on a Windows 7 machine with a GTX Titan (work computer). Thanks!
type chrome://flags in chrome address bar, and look for settings #ignore-gpu-blacklist
this happened to me, suddenly my gpu was added to blacklist and chrome reverted to software rendering..
For me running google-chrome on linux I needed to enable Use hardware acceleration when available in chrome://settings
