24 Feb Troubleshooting graphical glitches in Firefox
A few days ago my Firefox browser started having serious graphical glitches when viewing certain hardware accelerated web applications such as YouTube. Naturally, the first thing I tried to do was disable hardware acceleration, and that fixed the problem. But no one likes to disable HWA, right? So I dug deeper.
Most results on Google suggest to go to `about:support` to figure something out, or disable WebGL in `about:config`. I tried upgrading my graphics drivers and rolling back, using [Display Driver Uninstaller](https://www.guru3d.com/files-details/display-driver-uninstaller-download.html) too. I even tried re-seating my GPU twice.
Finally, I found that the graphical glitches don't transfer to a different monitor. At this point, I switched the refresh rate from 144Hz to 120Hz, and the problems went away immediately. ¯\\\_(ツ)\_/¯
