Cant hide columns in chrome dev tools network tab

After a recent update to Chrome dev (88.0.4315.5), all the possible columns in the network tab are shown and i cant hide any of them. I've tried right clicking the header and unchecking but nothing changes.
here's a screenshot of the problem
Also encountered this problem today, I'm using Chromium Nightly build.
Downgraded to stable, and everything fixed

Black screen in chrome after sleep

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

Chrome Dev Tools: tooltips are not displaying correctly

When I hover over the inspect tool or over the styles.css link in the styles tab, the tooltip is not displaying correctly. It is too far to the right and cut off. I have tried un-installing and re-installing Chrome. I have tried disabling all my extensions. I can't figure out what's causing this. Is this just a bug? I have already submitted this to the Google Chrome help. I am running OS X El Capitan 10.11.6 and Chrome Version 67.0.3396.62.
Screenshot of dev tools
I finally solved this by turning off "Use hardware acceleration when available" in my Chrome settings.
This was a bug in version 79. You have to update your Google Chrome to version 80+.

Chrome remote debug display issue

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?

Dev Tools auto-complete doesn't work on chrome 35, ubuntu 14.04

After update to chrome 35, autocomplete in dev tools doesn't work. Is it only my issue?
Checked windows and mac, all works..
I've got some similar problems, but just on Styles panel on Elements tab. Here, I've opened an issue just to this case:
https://code.google.com/p/chromium/issues/detail?id=376763&thanks=376763&ts=1400852713
I know it's not a solution, but it's the best we can do. We have to wait for someone at google (or that's involved with chromium project) fix it, and then release a new version patching it.
An alternative is using Chromium from ubuntu Software Center for now (it's still at version 34, so the autocomplete works): https://apps.ubuntu.com/cat/applications/chromium-browser/
UPDATE
This bug has been fixed on version 36
The issue has been fixed in the beta version.
(works in the current version: 36.0.1985.49 beta)
Can be download from http://www.google.com/intl/en/chrome/browser/beta.html
edit:
Considering the initial message, I assumed the problem was to pop the autocomplete box in the source files search as i enter in this issue. If the problem ain't relative to this, sorry.
In the last version the auto-completion menu in dev tools doesn't appears automatically anymore, u need to press cmd+P or cmd+O (mac) to open it.
I've got the same problem. It's really annoying.
Besides, on the Elements tab, when you double click the attribute of an arbitrary tag, the attribute is automatically emptied, which, i think, is not really expected.
Hope these issues get solved as quickly as possible.
