*** If you're not sure this is actually a bug, instead post about it at https://discuss.kde.org If you're reporting a crash, attach a backtrace with debug symbols; see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** SUMMARY STEPS TO REPRODUCE 1. Have "dim automatically" enabled (e.g. after 30s to see it quickly) 2. Start video playback (e.g. in Firefox) 3. Confirm in "Power and Battery" tray widget that sleep and screen locking are blocked due to FF "video-playing" 4. Wait period specified in 1. OBSERVED RESULT Screen dims after 30s EXPECTED RESULT Screen is not dimmed for as long as the video is playing. SOFTWARE/OS VERSIONS Operating System: Fedora Linux 40 KDE Plasma Version: 6.1.1 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 Kernel Version: 6.9.6-200.fc40.x86_64 (64-bit) Graphics Platform: Wayland ADDITIONAL INFORMATION I see no UX reason why screen should get dimmed whilst the video is playing. It just doesn't make any sense to reduce the experience, especially when watching full screen and not performing any mouse/keyboard actions.
Is Firefox running in a Flatpak? If so, it may be Bug 486506.
You're indubitably right. Tested quickly with VLC from rpm and it doesn't seem to be an issue there. *** This bug has been marked as a duplicate of bug 486506 ***
