Description dauntless 2021-10-26 01:07:49 UTC

SUMMARY
Using Flatpak Chromium v95.0.4638.54 and have tested watching full-screen videos, found screen locking and dimming still occurs. 

STEPS TO REPRODUCE
1. Set screen locking or dimming to 1 min
2. Full-screen any YouTube video (also found the same with Jellyfin)

OBSERVED RESULT
It'll still screen lock/dim.

EXPECTED RESULT
Unlike watching full-screen videos in VLC, FreeTube, etc which prevents locking/dimming whilst watching.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kubuntu 21.10
(available in About System)
KDE Plasma Version: 5.23.1
KDE Frameworks Version: 5.87.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
I use a secondary monitor for my laptop also.

This would be a bug in Chrome/Chromium itself. it's up to the app to inhibit screen dimming and locking. Firefox does, FWIW.
