Google Chrome freezes during fullscreen due to hardware acceleration on Ubuntu 18.04

I am using Ubuntu 18.04 on Dell Vostro 3546.

uname -a
Linux vaishnavi-laptop 4.15.0-124-generic #127-Ubuntu SMP Fri Nov 6 10:54:43 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Whenever I turn on hardware acceleration in chrome for GMeet change background, I experince slowness only in Chrome, not in the system. To be specific, when I enter fullscreen either by Fn+F11 or by double-click/"fullscreen"-button, Chrome gets stuck. Only option is to restart chrome. When hardware acceleration is off, no problem, but I need it for GMeet.

• chrome://gpu when hardware acceleration is on:
  

Please help me !!!

I accidentally solved this problem by going to:

Settings --> Devices --> Screen Display --> Resolution

and changed the resolution to the lowest, then changed it back to the highest.
I'm not 100% sure about this, but it worked for me.
I don't know how this worked, but anyway, now my issue is fixed.

I had the same issue both on Windows and on Ubuntu. To clarify, it happed whenever chrome went full screen, and only occasionally when the laptop was unplugged, so I believe that the issue was with the discrete GPU.

A recent driver update solved it.

If it is not the case for you, I'd suggest Testing on the latest Ubuntu version.

This is a solution for the same problem except in Windows

Solution:

1. Go to settings/system/display/Graphics Settings

2. Choose the classic app option, and browse and select chrome.exe (should be in your chrome installation directory)

3. Press Options/High Performance

4. Enable Hardware Acceleration in chrome of course

5. Enjoy
