Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
8793 frames in 5.0 seconds = 1758.569 FPS
doesn't even give any error, but the windows stayes black.
I use xfce 4.12 and have tryed 3 different compositors, with all i get the same
black window. Resizing the windows does not help (that i read in many bug
reports).
kernel is 4.0.0-rc6, xserver is 1.16.4, mesa is 10.6-git and radeon driver is
7.5.0
There are zero errors in the terminal or logfiles.
