Description wbqq 2023-01-27 17:25:51 UTC 
SUMMARY
x11 only bug
In wayland when you press meta+L screen instantly turns black untill the screen locker ui gets loaded. In x11 screen stays still and gives no visual feedback about the fact that meta+L was pressed untill the screen locker ui gets loaded. On my weak old laptop especially in powersave mode loading screen locker ui can take 3-5 seconds so i would like x11 session to make screen black untill screen locker ui is loaded (idk if its a bug or just whishlist)


STEPS TO REPRODUCE
0. have an old weak core i3'ish laptop or just turn on powersaving mode
1. enter plasma x11 session
2. press meta + L to lock the screen

OBSERVED RESULT
have to wait 3 seconds guessing if the key was even pressed, no visual feedback, though screen locker then finally appears 

EXPECTED RESULT
screen turns black for 3 secons so i know its loading, then screen locker ui appears
