https://bugs.kde.org/show_bug.cgi?id=396345 --- Comment #13 from john Terragon --- Isn't that something that an application can set/change to give a suggestion to the wm (the hint part...)? Anyways, let me know if there's something else I can try. I sync'ed the two roots with another system, a desktop one (and more recent, a 4770k I think). I see the same behavior, it's about triple the cpu usage by kwin 5.13 wrt to 5.12. -- You are receiving this mail because: You are watching all bug changes.

So, I did the following: 1) wmctrl -lp to get all the winids of firefox's windows 2) xev -id on each and everyone of them (just to be sure) When I do "xev -id " xev just stand there without reporting anything which I guess means the window isn't generating any event, right?

https://bugs.kde.org/show_bug.cgi?id=396345 --- Comment #6 from john Terragon --- If that's the reason, why doesn't firefox "victimize" kwin 5.12? I have now two root filesystems (I use btrfs). Both of them have the same packages and at the same versions. Except one root has plasma 5.12 and the other has plasma 5.13. And the problem is only with plasma 5.13... -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=396345 --- Comment #5 from Martin Flöser --- I see, so the problem is probably with firefox, not with KWin. KWin is just a victim of the stupid things firefox does. You can use xev -id to monitor which events it creates. I assume it's constantly updating e.g. window title. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=396345 --- Comment #4 from john Terragon --- Disabling the blu effect brings down the cpu usage by about 7%, which leaves it still above 30. And, btw, the only things that the blur effects blurs are the plasma decorations. Windows are not blurred, not even when they become semi-transparent when I drag them around. Another possible clue: 30 dolphin windows do not cause kwin to use much cpu, 30 firefox windows (and all pretty much static, that is without any change of the content like in ads, animation etc) cause the 40% cpu activity. Right now we are at 80% cpu activity for kwin! Also firefox seems to have higher cpu activity (higher than it has under 5.12). -- You are receiving this mail because: You are watching all bug changes.
