Hi George
IDL is running fine with 2.3.2.1 (and If I recall correctly it has been running fine since 2.2.0). Basically, what happens now (2.3.3) is that all graphics windows appear black (normal GUI widgets are fine). The correct image shows up briefly, and then becomes black.
Can you tell me what the application is doing when the failure occurs (around when the final surface destroy occurs)? Does it
withdraw/unmap and remap windows?
This happens every time the graphics are drawn. I'm afraid I don't have any more details to tell you since IDL is commercial and I don't have access to the source code. If I recall correctly, you may be able to resize the window and
temporarily see drawing occur, depending on how IDL uses GLX.
Yes, this is exactly what happens. When I resize the window the image flashes briefly and then turns black again.
All the best, Ricardo
Hi Richardo,
This particular problem has not been resolved yet. Did IDL work
correctly with any previous XQuartz releases?
Can you tell me what the application is doing when the failure occurs
(around when the final surface destroy occurs)? Does it
withdraw/unmap and remap windows?
The new libGL seems to work better in general for most users, but this
issue is causing problems. We have a test case fortunately, and
understand the problem fairly well, but a simple and correct solution
isn't clear yet. I will try to do some more work on this issue. My
understanding and testing has indicated it's not a new problem, but
the problem's exact behavior is slightly different. The end result is
that drawings don't appear that should.
If I recall correctly, you may be able to resize the window and
temporarily see drawing occur, depending on how IDL uses GLX.
Thanks for letting us know.
