I just recompiled KWin against the mesa shipped by debian testing and the
problem is still present. Here the debug output:

libEGL debug: EGL search path is /usr/lib/egl
libEGL debug: added /usr/lib/egl/egl_gallium.so to module array
libEGL debug: added /usr/lib/egl/egl_dri2.so to module array
libEGL debug: added /usr/lib/egl/egl_glx.so to module array
libEGL debug: dlopen(/usr/lib/egl/egl_gallium.so)
libEGL info: use X11 for display 0x9a00c0
libEGL debug: searching for pipe module r600
libEGL debug: loaded /usr/lib/egl/pipe_r600.so
libEGL debug: the best driver is Gallium (score 100)
libEGL debug: searching for st module GLESv2
libEGL debug: loaded /usr/lib/egl/st_GLESv2.so


Testing with egl_dri2 is not possible, I get the following error message:

libEGL debug: dlopen(/usr/lib/egl/egl_dri2.so)
libEGL debug: failed to open ${ORIGIN}/dri/r600_dri.so:
${ORIGIN}/dri/r600_dri.so: cannot open shared object file: No such file or
directory

libEGL warning: DRI2: failed to open any driver (search paths ${ORIGIN}/dri)


Further testing, like adding patches and bisecting, I will not be able to do
before I have time for it (maybe at the weekend), but as it is a driver from
distribution packages I cannot apply the patches on what I have here. I would
have to switch to self compiled mesa. And as already said, I am not able to
reproduce with 7.11, so I don't know whether I will be able to reproduce on
7.10 branch when self-compile.
