As I already wrote I could not find the reason of the misbehavior of MSEgui
with opensource EXA-Pixmaps drivers although I spent many days with the
problem. If you find a bug in MSEgui it will be fixed as soon as possible.

I don't think so, the problem probably is this:
Nobody has actively worked on EXA for years.
I again unsuccessfully spent several days to try to find a bug in MSEgui, try
to find a workaround or to find a small testapplication which shows the
MSEgui paints on a pixmap with the size of the update region which is moved to
the window by xcopyarea() after the drawing is complete.
The attached application draws a diagonal line over a grid cell. Every 2
seconds the cell will be invalidated and refreshed. At startup the display is
OK, after 2 seconds the diagonal line will be truncated. This has been
reproduced on three installations.
If the test-program is started with any command line parameter
(ex. "./radeonline abc" the drawing of the blue rectangle is disabled. Two of
the three installations always show the diagonal line in this mode with full
length, one truncates it after 2 seconds.
With the option "EXAPixmaps" "off" in xorg.conf all is OK.
The simplified testprogram from
https://bugs.freedesktop.org/show_bug.cgi?id=69543 shows a distorted display also by directly drawing to the window so the double
buffering probably is not the culprit.

Probably an EXA issue. Option "EXAPixmaps" "off" mostly avoids the hardware
acceleration paths in EXA.

Who is responsible for "Server/Acceleration/EXA"?

What to do now? What do you recommend?
