Browser: Snap Firefox (most recent version) System: KUbuntu 22.04 LTS Issue: With Snap Firefox maximized on 1440p monitor, the VTT would display a black background, and tokens would display incorrectly and distorted. The problem did not present on ungoogled-chromium, or on Snap Firefox at 1080p. Solution: After extensive tinkering and discussion with email support staff I was able to use the VTT maximized on 1440p with the Flatpak version of Firefox. Attempted fixes that did not work: * Starting Snap Firefox in Safe Mode. * Tinkering with various about:config files as suggested in the r20 troubleshooting pages * Manually disabling all extensions and themes, clearing cache. Another solution that worked *with* Snap Firefox was using the Default User Profile (instead of my user profile) that comes with Firefox. Having to use a fresh profile every time I want to use r20 is annoying though so I suggest just using a different packaging of Firefox.
