Description ryu.ketsueki 2020-08-30 01:06:14 UTC
SUMMARY
This is an issue that happens with anything that uses KWin's blur but is more noticeable with window decorations that use rounded corners, such as Aurorae or Breeze forks like Sierra Breeze, Breeze Enhanced and Breezeway. If the corner radius is bigger than normal Breeze, the blur behind the titlebar still takes the shape for normal Breeze, with a sharp corner. This can be fixed by allowing the blur to take shape of the corner or give an option to disable blur for window decorations.

STEPS TO REPRODUCE
1. Use any window decoration with round corners
2. Enable blur effect on KWin effects

OBSERVED RESULT
Sharp blur corner near round corners
