--- Comment #9 from Michel Dänzer <michel at daenzer.net> ---
I think this is because the glXWaitX implementation in Mesa isn't reliable.
xfwm4 relies on it to synchronize between X11 protocol drawing to a pixmap and
sampling from an OpenGL texture bound to the corresponding GLXPixmap via
GLX_EXT_texture_from_pixmap.
