https://bugs.kde.org/show_bug.cgi?id=447797 --- Comment #13 from Zamundaaa --- To explain why I put this in CC for the commit, while there's probably still some driver bug (with some flicker being visible in Weston), it fixes most of the flicker on kwin_wayland. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=447797 --- Comment #11 from ob --- (In reply to Zamundaaa from comment #10) The desktop icon/file/folder thing is definitely exclusive to the Wayland session. In X11, it animates fading in attached the cursor after the icon immediately disappears on the desktop or in the folder. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=447797 Zamundaaa changed: What|Removed |Added Status|REPORTED|RESOLVED Resolution|--- |UPSTREAM --- Comment #10 from Zamundaaa --- As this can be reproduced with Xorg, kwin_wayland and also weston is almost certain that this is a driver bug - it seems to me like it updates the cursor texture and position asynchronously. I opened an issue with amd: https://gitlab.freedesktop.org/drm/amd/-/issues/1968 (In reply to Patrick Silva from comment #4) > Same bug when I start to drag an icon on desktop. I use intel iGPU. > > SOFTWARE/OS VERSIIONS > Operating System: Arch Linux > KDE Plasma Version: 5.24.3 > KDE Frameworks Version: 5.92.0 > Qt Version: 5.15.3 > Graphics Platform: Wayland I think that is a Qt bug, there's a weird similar issue in Dolphin and Gwenview as well - but not in Firefox when dragging an image. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=447797 --- Comment #1 from unixst...@protonmail.com --- I launched kwin_wayland with --exit-with-session konsole as well as with the WAYLAND_DEBUG=1 environment variable. This is the output (a bit trimmed). I tried to reproduce the issue (and successfully so!) by causing the cursor state to change.
