I’ve got the following problem. Characters drawn with OpenGL into a window disappear when I move the window from one screen to another in a two monitor Xinerama setup. The characters reappear if I move the window back to the first screen. The character drawing stops at the exact border between the two screens.
See attached screenshots.
Using TwinView the characters do not disappear.
I also attached an apitrace trace file of the execution of the test program.
Hardware: 2 monitors on one NVIDIA GPU Quadro K2000
Software: CentOs release 6.3 (Final), Linux x64 (AMD64/EM64T) Display Driver 319.49
If you need more information please let me know.
Thanks a lot!
