Since late April 2010 I've been having screen tearing and other problems with rendering in World of Warcraft. By "screen tearing" I mean that rapidly-shifting areas of the screen are rendered as polygons of solid color. This usually affects what I think of as the background layer of the window, rather than any foreground window that happens to be open. Seems to be worse in certain areas of the game world, e.g. Crystalsong Forest, where I imagine textures are more complex.
By "other problems" I mean that square areas of the landscape sometimes appear to be rendered with the wrong z coordinate, so a square of ground will appear to be hovering in midair. This seems to happen most often right after entry to the game world.
Turning on VSync doesn't fix the problem. Problem appears whether in windowed mode or full-screen mode.
I've upgraded Ubuntu to 10.04 (lucid) with no relief. At this point I've got fglrx 8.723.1 (latest from ATI) and wine 1.1.43.
