The crash reports are from FxR v5 and it seems related to a Android hard acceleration bug (similar to #1959)
@Softvision-RemusDranca or @Softvision-GeluHaiduc Can you check test this one on a Focus device? It may have been already fixed by #2184

[Softvision-GeluHaiduc]

I managed to partially reproduce the issue using Firefox Reality version 7 RC3 (7b66fb1) installed on HTC Vive Focus Plus.
After more than 1 hour of stressing the app navigating Youtube and quitting and resuming the app at 1 video the Black screen with the error message appeared, the logcat file can be found here and the screen recording here.
After some more stressing in which I created tabs and windows and again quitting and resuming the app crashed, the logcat file is here and the crash report here.

Thanks for the info @Softvision-GeluHaiduc!

I created a separate issue for the crash #2383. It's different from the one that @kaipinglee reported, which seems fixed with the #2184

[MortimerGoro]

Fixed in #2482

[Softvision-GeluHaiduc]

I have verified this issue with the latest Firefox Reality version 8-40101959 (3c2a71e) installed on the HTC Vive Focus and HTC Vive Focus Plus headsets.
From what we tested the issue is no longer reproducible at this time, but keep in mind that it is an intermittent issue. If it reappears in the future we will file a new issue for that.
