Bug ID: 408949
Summary: Black border around windows with blur enabled
Product: kwin
Version: 5.16.1
Platform: Archlinux Packages

Status: REPORTED
Severity: normal

This black border occurs on all 4 corners.
SUMMARY
There is an ugly black border around the rounded edges when blur is enabled
with any theme that isn't Breeze (Tested with Materia KDE and Arc KDE).
Disabling blur makes this bug go away. Have seen other reports of this bug so
its legit. This bug didn't exist on Plasma prior to version 5.16. Also, this
border occurs on GTK applications as well. I read somewhere that this was as a
result of blur being rendered for window shadows but I'm not sure.
STEPS TO REPRODUCE
1. Enable blur
OBSERVED RESULT
Black border at rounded corners
EXPECTED RESULT
Rounded corners
