Since several years MSEgui doesn't work with radeon driver anymore. http://sourceforge.net/projects/mseide-msegui/ https://bugs.launchpad.net/ubuntu/+bug/373781 https://bugzilla.novell.com/show_bug.cgi?id=690766 https://bugzilla.novell.com/show_bug.cgi?id=852944 https://bugs.freedesktop.org/show_bug.cgi?id=69543 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 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. Comment 1 Michel Dänzer 2014-09-24 02:41:18 UTC Probably an EXA issue. Option "EXAPixmaps" "off" mostly avoids the hardware acceleration paths in EXA. Comment 2 Martin Schreiber 2014-09-24 05:47:09 UTC Who is responsible for "Server/Acceleration/EXA"? Comment 3 Michel Dänzer 2014-09-24 06:14:08 UTC Nobody has actively worked on EXA for years. Comment 4 Martin Schreiber 2014-09-24 06:36:36 UTC What to do now? What do you recommend? " No further actions since then...
