--- Comment #17 from Bernd Steinhauser <li...@bernd-steinhauser.de> --- Well, there is definitely something wrong with kwin as well, but I have yet to find out the details. For example, sometimes it does not respond to a double-click on the window decoration, which should lead to a maximization (can try 3 times and I'm surely fast enough). After dragging the window a bit and trying again, it works instantly. But it's interesting that there seem to be quite a few triggers for the cursor lag and afaics it's always accompanied by a strong increase in plasmashells cpu usage. It's also interesting to see that it's always in two processes simultaneously: The first and second started process (thread?). One of the triggers I found for example: Fiddling around with firefox, sometimes bringing up a tooltip or context menu results in such stuttering. I have no idea why plasmashell would be involved there. Even loading a new website or just opening a new tab results in a strong increase in plasmashell's cpu usage accompanied by the cursor lag. Why? Maybe, just maybe I could understand if it would be related to an compositing effect, but it happens without compositing as well. This is all very, very strange. -- You are receiving this mail because: You are watching all bug changes.
