I'm on latest mesa git and xf86-video-intel-git and it has been happening for a
while.
Here is a video: <a href="https://www.youtube.com/watch?v=al_gLzInYq0">https://www.youtube.com/watch?v=al_gLzInYq0</a>
sorry about the shaking and bad quality but as you can see in the video, the
effect vanishes when a screen recording application is running.
It also only happens with compositing, (both xrender and opengl compositing)
and vanishes when compositing is disabled.
I didn't think much about it, because it only affected glxgears and no other
application, but then I tested zetrix in wine:
<a href="http://www.download-central.ws/Win32/Tetris/ZetriX/">http://www.download-central.ws/Win32/Tetris/ZetriX/</a> and I saw the same effect.
It doesn't work right anyway, i.e. fonts don't show, but the background
animation has these line artifacts too.
And then I have no idea if this is the correct place here at radeonsi.</pre>
