This seems to affect Chrome, Brave and Opera.
The remedy is to disable GPU acceleration. Make sure that the browser is up to date (with APT or SNAP) before attempting these fixes.
For chrome
Disable GPU acceleration via the terminal:
# Open a terminal and run Chrome with the --disable-gpu flag: google-chrome --disable-gpu.
Once Chrome opens
- Settings->System
- turn off "Use hardware acceleration when available".
For a more stable but potentially slower experience, you can try this command instead:
google-chrome --use-gl=swiftshader --disable-gpu-rasterization --disable-zero-copy
There was a similar fix for Brave:
# Run this command: brave --disable-gpu
When Brave starts:
- Click the three lines on the right
- Choose Settings
- Click the three lines on the left
- Choose System
- Toggle GPU acceleration
For Opera use the following:
opera --disable-gpu --disable-gpu-compositing --safe-mode
- Navigate to: opera://settings/system
- Disable GPU acceleration
