Test application
Since several years MSEgui doesn't work with radeon driver anymore.

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
problems.
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

shows a distorted display also by directly drawing to the window so the double
buffering probably is not the culprit.</pre>
