--- Comment #45 from H. Verbeet hverbeet@gmail.com 2009-01-28 04:08:48 --- I'm pretty sure the issue is in Wine. Does the log contain any FIXMEs from surface_load_ds_location()? Typically you'd start with looking at how the frame is rendered (ie, dumping the backbuffer and depth buffer for each subframe) and then matching that against the log output.
