ADDITIONAL INFORMATION
Comment 1 Vlad Zahorodnii 2025-05-27 11:12:56 UTC
kwin has a mechanism to avoid that glitch but an application has to opt in into the _NET_WM_SYNC_REQUEST protocol. Jetbrains Toolbox doesn't do that, so you see that glitch. Not a lot that we can do from the kwin side, it's a fundamental issue with X11.
Comment 2 Vlad Zahorodnii 2025-05-27 11:14:01 UTC
I suggest to report this issue to Jetbrains developers asking to implement support for _NET_WM_SYNC_REQUEST, or even better look into supporting wayland mode natively. :)
