--- Comment #16 from Martin Flöser <mgraess...@kde.org> --- I was able to reproduce the issue and investigate it. The problem is caused by an invalid sized WindowQuad of the decoration shadow. So the change in shadow size in 5.12 might have triggered it. To make it clear: this is not a bug in breeze! Breeze is just the one who triggers the bug in KWin. -- You are receiving this mail because: You are watching all bug changes.
