If you run kwin with KWIN_USE_BUFFER_AGE=0, does flickering occur? (In reply to Vlad Zagorodniy from comment #1) > If you run kwin with KWIN_USE_BUFFER_AGE=0, does flickering occur? I restarted kwin using that variable but I still have the same problem. I open a game, disable compositing after it started, close the game, reenable compositing and when I open a new window I can see black artifacts in the border that are gone when I move the mouse over the affected areas. The bug is quite arbitrary, sometimes it creates black artifacts in the window borders, other times it cause flickering when opening widnows. I can't reproduce exactly this bug. However, for some period of time I was noticing similar bug. If you toggle compositing couple times, the screen becomes completely black. The only thing that's visible is the cursor. After recent updates (BTW, I use Arch) the issue seem to be gone. In either case, I'm not sure that this is a kwin bug, e.g. buffer age related. It's worth looking down the stack. *** This bug has been marked as a duplicate of bug 404375 *** |
