I can confirm this bug. To solve the problem i use the options:
Option "XaaNoScreenToScreenCopy" Option "XaaNoSolidFillRect"
in the xorg.conf
GLX is also effected by the bug. Glxgears shows a blank screen and after closing it reports:
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"
X11 works normal after rebooting Linux
