--- Comment #1 from odzi...@gmail.com --- I think I may have found the cause of this issue. I noticed that if I had an application open but minimized, simply hovering over the task manager would not fix the issue. What would fix the issue was unminimizing the window. If all the application I had open were visible on the desktop when suspending/resuming kwin, the fps drops would not occur and my fps would stay at a constant 100. If I suspended/resumed with minimized applications, the issue would occur until all the applications were unminimized. This led me to believe that the issue must have been caused by the thumbnails being generated by the compositor. My "Keep window thumbnails" setting was originally set to "Only for shown windows" but after switching it to "Always" I was no longer experiencing this issue. I have tested it with manually suspending/resuming kwin, having an application block compositing and then closing it and suspending my pc. Issue did not occur a single time. -- You are receiving this mail because: You are watching all bug changes.
