https://bugs.kde.org/show_bug.cgi?id=360137 --- Comment #24 from Bernd Steinhauser --- For testing purposes, I downgraded Plasma to 5.5.5. I do still see the same behavior. I'm pretty sure that I didn't see it previously when I ran 5.5.x, because a laggy behavior like

https://bugs.kde.org/show_bug.cgi?id=360137 --- Comment #18 from Thomas Lübking --- Doubleclick sounds like related to bug #357450 but should be resolved in your KWin? About the cross process CPU load I could imagine that this is due to a swapping race in two GL
