https://bugs.kde.org/show_bug.cgi?id=462002 --- Comment #7 from gudvinr+...@gmail.com --- https://gitlab.freedesktop.org/wayland/weston/-/issues/602 I probably found upstream-ish issue about that -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=462002 --- Comment #4 from gudvinr+...@gmail.com --- Night color is only one of the cases when it happens. It's not even that important tbh because I don't turn it on and off manually anyway. So I am fine with that. And it happened before too. But I also get stutters without night color being turned on or when it's fully transitioned (as I described in my previous message). I haven't had these on 5.25 with wayland and X11 and I don't remember having these issues on X11 before that. But I started having issues somewhere around 5.26 release I think. I can't pinpoint exact date or release because at first I thought it is same thing caused by night color that I was seeing before. But now I can say for sure that it isn't. Also around that time I started to have performance issues I described in bug 463718, that may or may not be related to this one. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=462002 Vlad Zahorodnii changed: What|Removed |Added Resolution|--- |NOT A BUG Status|REPORTED|RESOLVED --- Comment #3 from Vlad Zahorodnii --- Night color changes the gamma ramp which is equivalent to modesetting and it can cause stuttering. I don't think that we can do much about it on kwin side besides using atomic modesetting apis, which we already do. If there are still issues, it sounds like a kernel bug, but they probably can't do much about it either. Another option is to perform the transition in software, but we lack the needed infrastructure and I'm not sure that the code complexity is worth it. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=462002 --- Comment #2 from gudvinr+...@gmail.com --- I noticed that I can reproduce issue more easily when I move mouse over certain windows. E.g. discord (xwayland) or firefox (wayland native). With discord I get almost 100% reproducibility if I launch an app and start moving mouse around in discord window. I had same stutter right now, while writing issue in firefox. But once I opened OBS to record, it went away when I opened obs and went back to firefox. Also sometimes that happens after I switch activities back and forth while moving cursor. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=462002 --- Comment #1 from gudvinr+...@gmail.com --- Actually, it might be caused by Night Colour because I tried to turn it on and off and while it is transitioning. But I think it is different issue because by the time I see these hiccups, it is already fully transitioned. -- You are receiving this mail because: You are watching all bug changes.
