I think I found a solution/workaround. Disabling "use vsync" and kwins CPU usage is back to normal (even with desktop effects enabled). Tristan, could you try that too, pls?
I'm using a nvidia graphics card, maybe this has something to do with it. Maybe vsync shouldn't be enabled by default if it is causing problems. -- KDM permanently needs 50% CPU https://bugs.launchpad.net/bugs/202129 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
