--- Comment #3 from Ancoron <ancoron.lucife...@gmail.com> --- I was now able to reproduce the issue with a completely new user setup and indeed, it appears to be happening only for setups with multiple Activities, but not necessarily only after Activity switching (just takes longer to get triggered). Also, this new user setup did not have any custom KWin scripts installed, which could have messed with it. The issue does not occur when compositor is turned off, so it had to do with either the compositor itself or some of the desktop effects, which I then tested thoroughly. Finally, I found that the effect "Slide Back" in section "Focus" is causing this bug. After disabling the effect, the originally affected user session immediately became free of this issue. Although I'll observe it further, it looks like I have found at least one candidate here. Also, I am still running the Mudeer Tiling KWin script without any issue. -- You are receiving this mail because: You are watching all bug changes.
