mesa-10.1? I believe that this is an issue in mesa, introduced with 10.1. Can you please check that downgrading to 10.0 (possibly maybe even an older 10.0, say 10.0.3 or older) is required. I also had a very similar issue (which also evidenced itself via other graphical glitches), and it appears that using Mesa 9.2.5 fixes this. Going back to mesa 10.0.3 solved the problem, it is indeed a mesa bug then. There have been other issues that only occur with the combination of mesa-10.1 and Xorg-1.15 upgrades. That may be a clue here as well. Hi Nicolas, This is due to a bug in our MSAA code, which Eric fixed in Mesa master today. However, the fact KWin is using multisampling at all is due to a bug in the X server, which was fixed in xserver 1.15.1 or 1.14.6. Upgrading either component will make the problem go away. Alternatively, if you need a workaround and can't easily upgrade, you can do: KWIN_OPENGL_INTERFACE=egl kwin --replace & Sorry for the trouble. *** This bug has been marked as a duplicate of bug 77207 *** |
