piotr.c.ma...@gmail.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |piotr.c.ma...@gmail.com --- Comment #13 from piotr.c.ma...@gmail.com --- I am experiencing the same issues without running , just running apps that are not wayland native. The apps i have identified so far are : * All IntelliJ related products (unless i chose JDK-23 and enable experimental wayland support - the app is no longer listed in xlsclients then, and the problem is not present) * Smath (a mathcad-like application using mono) I suspect that probably every app that is listed when i run the "xlsclients" command causes this problem Like i mentioned before running these apps causes sudden slowdown of the entire desktop after some time (like a minute or two). Closing these apps does not resolve the issue. The kwin_wayland process takes around 15% of CPU time, even when showing only wallpaper, but the UI slows down considerably more than these 15% in my opinion. When i enable the "Show FPS" desktop effect (i do not know why "show paint" effect does not work for me) the "Paint amount" rises to constant 100% and does not go down even if i close every window. Issuing "kwin_wayland --replace" solves the issue but also restarts every other application. -- You are receiving this mail because: You are watching all bug changes.
