Yes, and they said that a quick way to find out is to set: Option "EXAPixmaps" "false" in the device section of xorg.conf, restart X, and then see if it stops the problem. There also is an "unconfirmed" report that the problem was not present in xserver 1.10.x (yet another suggests 1.10.6 is affected): https://bugs.freedesktop.org/show_bug.cgi?id=43764 Since this appears to be an EXA bug, it should not be present in the older, traditional, XAA acceleration method: Option "AccelMethod" "XAA" provided XAA is (still) available for the given video card driver. It would also be interesting to know what performance hit (if any) is incurred by using XAA instead of EXA on a modern system (glxgears, scrolling with a browser, etc). On older hardware, XAA can sometimes even be a tad faster than EXA.
