It does use OpenGL. The application opens multiple image squence windows for comparison. Just find it a bit strange that it 1: works sometime, 2: works perfectly when compiled on a SuSE7.1 system (X4.2, mesa 3.4) and then run on this newer system. btw, I have mesa 4.0.3 if it matters and I've run the demo's and set the permission and mesa has given me it's blessing.

then that is it and it exits.  The other 50% of the time it runs
perfectly.  NOTE: I compiled the application using gcc3.1.  If I compile
it on a SuSE7.1 system with the SuSE X 4.2.0 packages and then run it on
a SuSE8.1 system it works fine.  Also note: this happens on all of the
SuSe8.1 system I have (about 20 or so) so it can't be specific to Video
card (they all have various cards).  Bellow is the last lines of an
strace on the application.  Note: DRI is setup and working and loads
just fine from the looks of the X log.

Any clues??


Sounds very interesting. What does this application do? does it use libGl and friends or only does 2D stuff? If you run the X server on the systems in vga mode (no acceleration) does it still behave the same?
