Just found that just disabling and renabling desktop effects also corrects the problem. I'm using Intel graphics hardware/drivers (openSUSE 12.2) You set the version information to 4.9.1. Is this correct? OpenSUSE 12.2 is not shipping 4.9 yet. If it is really 4.9 please run qdbus org.kde.kwin /KWin supportInformation once when the issue occurs and once when it is ok and attach the information here Created attachment 74299 [details] Output Yes I'm on 4.9.1 (using repo http://download.opensuse.org/repositories/KDE:/Release:/49/openSUSE_12.2/) kwin -v Qt: 4.8.3 KDE Development Platform: 4.9.1 "release 561" KWin: 4.9.1 "release 561" Created attachment 74300 [details]

There is not much we can do about it. It's with OpenGL quite normal that you see these lines (it is THE argument for client side window decorations). The fact that restarting the OpenGL compositor affects it, might be by pure chance and might be related to some internal state inside the driver. But it's nothing we can actually trigger. Overall it's more a CANTFIX from our side as it's a known OpenGL limitation. That looks like an upstream bug, because kwin /is/ using GL_CLAMP_TO_EDGE ? (*the* one single error in gl usage responsible for this bug; so much that the nvidia blob had for years silently mapped the call and now still has a setting and an env for it ;-) @Martin Isn't this bug #257566? yeah it is *** This bug has been marked as a duplicate of bug 257566 *** |
