on Ubuntu 10.04 x64 with ati-driver-installer-11-3-x86.x86_64.run
Hi again,
I return with another strange bug, which from time to time blocks the thread doing the rendering in the function glGetTexImage.
It is difficult to reproduce, it happens quite often but at random intervals after the aplication starts. The aplication can be deblocked if the xserver updates the screen for instance move a window or switch to a different window. It can also deblock if in an ssh terminal you export the display and run glxinfo (although some times the glxinfo blocks also by doing this).
I can not include a small test code, I wasn't able to reproduce it in a small test app.
The system is: Intel i5-2400 and ATI HD 5870 or 6970 (the video card seems not to make a difference) on Ubuntu 10.04 x64 with ati-driver-installer-11-3-x86.x86_64.run
Thanks!
PS: Although it will not help too much, here is a backtrace from my application:
