Description Kai Uwe Broulik 2021-11-03 18:11:49 UTC
SUMMARY
The logout greeter backgound is solid black as opposed to having a blurred background.

STEPS TO REPRODUCE
1. Leave session

OBSERVED RESULT
Logout greeter background is solid black

EXPECTED RESULT
Logout greeter is gorgeously blurred

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: git master as of 2021-11-01 on X11

ADDITIONAL INFORMATION
Seems unrelated to Bug 444898 as even after fixing the fade animation the background is still black. However, you can see during the animation that it is blurred but seems not visible because of the opaque background it ends up with
