Pretty much fixed tearing on "c" will remain until we remove the "rather not so helpful" waitSync calls from the pixel copying branch (patch here, RR pending for the moment)
As for the CPU usage: the patch was never tested against 4.10 neither would it cleanly apply. If you can provide a callgrind dump, i can look into it, but there's little reason for CPU overhead on the buffer swapping paths (memory throughput esp. w/o flipping support, but that's not CPU related) It rather sounds as if you run into constant repaints - for whatever reason - and for 60% load on an i7 core rather unblocked (ie. beyond 60FPS) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069498 Title: KWin shows tearing despite of VSync To manage notifications about this bug go to: https://bugs.launchpad.net/kdebase-workspace/+bug/1069498/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
