Running kwin-x11 5.16.3-0ubuntu1~ubuntu19.04~ppa1. Uses 100% CPU. Killing & restarting using kwin --replace changes nothing. Running qdbus org.kde.KWin /KWin supportInformation hangs, then outputs Error: org.freedesktop.DBus.Error.NoReply Possibly related: everytime I'm typing Alt-tab, kwin outputs many (I guess as many as my windows) such lines: file:///usr/share/kwin/tabbox/present_windows/contents/ui/main.qml:89:21: QML RowLayout: Binding loop detected for property "height"
Things went back to normal after pkill -9 kwin ; kwin& I regularly need to do so, although I'm unsure how to reproduce this defect.
Seems to be related to https://bugs.kde.org/show_bug.cgi?id=364709 but that got actually fixed in 5.15. Did you activate Desktop Grid?
Thanks for your feedback. > Did you activate Desktop Grid? Yes, I did > Seems to be related to https://bugs.kde.org/show_bug.cgi?id=364709 but that got actually fixed in 5.15. All I can tell, is that my packages earlier than 5.15. I've switched to the "compact" (effect ? Dunno how these are called), to see how it goes.
1. Which version version do you use if not 5.16.3 and I suggest updating your packages. 2. Tell wether deactivating "Desktop Grid" helps
> 1. Which version version do you use if not 5.16.3 and I suggest updating your packages. I confirm I'm using version 5.16.3. I meant "more recent", not "earlier", sorry. > 2. Tell whether deactivating "Desktop Grid" helps What I can do is keep using my machine using the "compact" effect for a few days, and report back afterwards.
