Playing WoW with an RV350, kernel, Mesa and xorg driver from git; and I'm noticing that sometimes WoW's hardware cursor graphic is replaced by a square of random garbage (with working "hotspot" in top left corner). So my question is: which project is the best one to raise a bug against, please? The corruption persists after I exit WoW and can be fixed by restarting the X server, so my initial guess is the radeon xorg driver. But it is just a guess.

Any suggestions on how to restore the hardware cursor without restarting X would also be appreciated. I have occasionally seen the problem "fix itself" while continuing to play WoW, but far too infrequently to be practical.
