If I set "EnablePageFlip" to "on" and "TearFree" "off" -> only two side
If I set "EnablePageFlip" to "off" and comment "TearFree" -> Same issue
(black windows)
If I set "EnablePageFlip" to "off" and "TearFree" to "off"-> Same issue (black
If I comment all Options except "TearFree" to "on" -> only two side effects

Because the issue is random I cannot garantee all test results.

export LIBGL_ALWAYS_SOFTWARE=1 doesn't solve any side effect.

If I set "AccelMethod" to "off", it solves the issue and two side effects,
but when I play a video, it takes almost all CPU. With mplayer I cannot
maximize videos, With vlc if I maximize a video it runs too slow.

If I set "AccelMethod" to "EXA" I have the same issue.
