I have a problem: When rendering open gl content in window - everything is ok.
But in fullscreen mode - only 1/3 part of the screen is updated. It seems
like the root of the coords base is smth like (0, -400) instead of (0, 0).
Resolution - 1280x1024x24. Linux kernel version - 188.8.131.52. DRI is enabled
and compiled as modules. Can it be solved?
