Description Patrick Silva 2025-09-19 16:29:36 UTC 
STEPS TO REPRODUCE
1. open Power Management KCM
2. open the second combobox beside "Turn off screen:" and choose "When locked: Immediately"
3. apply the change
4. play a video in youtube with Chromium or Vivaldi
5. lock the screen by pressing the keyboard shortcut - I use meta+L

OBSERVED RESULT
the screen is locked but the screen remains on. The screen is turned off as expected if I minimize the browser window before locking the screen.

EXPECTED RESULT
the screen is locked and then the screen is immediately turned off

I guess the browser is inhibiting screen sleep, and we respect that in the lock screen. We could stop respecting it in the lock screen, because the reason for inhibiting screen sleep (to keep something visible) no longer applies.
