KWin crashes with the following message after switching from OpenGL 2.0 +
Raster to OpenGL 3.1 + Raster:

[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been
called
[xcb] Aborting, sorry about that.
kwin: xcb_io.c:274: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost'
failed.

As you can see in the kwin stdout output, radeonsi only supports OpenGL 2.1 in
Mesa 9.2. I suspect the problem happens when kwin tries to create an OpenGL 3.x
context, but I wonder if this is radeonsi specific — does it not happen e.g. if
you run kwin with LIBGL_ALWAYS_SOFTWARE=1 ?

I am not sure how to confirm it. I tried launching:

LIBGL_ALWAYS_SOFTWARE=1 kwin --replace > kwin_stdout_LIBGL_ALWAYS_SOFTWARE.txt
2> kwin_stderr_LIBGL_ALWAYS_SOFTWARE.txt

and it disabled desktop effects; then I tried to switch to OpenGL 3.1 + Raster
and Kwin crashed displaying 'report bug assignment'  window and then was
restarted automatically without effects. I could not enable effect anyhow.

kwin_stdout_LIBGL_ALWAYS_SOFTWARE.txt was empty.

 Pretty much old bug, is this still an issue with current mesa?

As per comment 4 radeonsi in 2013 probably didn't support the required OpenGL
support. Closing.
