seems to work correct.
DRI_PRIME=1 glxgears
shows only a black window, but the fps are shown in the terminal, i start from.
towo:lenovo-nb> LIBGL_DEBUG=verbose DRI_PRIME=1 glxgears
libGL: screen 0 does not appear to be DRI3 capable

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.
