Uh, unfortunately, no. I started trying to fix videos in looking glass games
but got ambushed by a swarm of bugs along the way :). I'm making some progress
and hope to clear out them all in a week or so, then I might look into this
regression later. If you are interested in wine 3d hacking, feel free to take
on it. I believe my IDirect3dDevice7_Load rewrite caused it. The rewritten
method uses some wined3d device methods, some of which probably directly or
indirectly trigger IWineD3DSurface_LoadLocation (maybe via loadtexture in
wined3d's texture.c) while there is no palette set (a situation it's usually
best to avoid). It may be that palette setting should simply be done earlier in
IDirect3dDevice7_Load / helper functions than it is now. It is surprising that
presense of ext_paletted_texture makes such a difference though. Possibly this
indicates a problem somewhere, such as either missing LoadLocation or unneeded
one in some of codepaths in wined3d. wined3d codepaths for paletted_texture
support are not unlikely to be buggy as most hardware nowadays doesn't support
it so it's worse tested than others, it needs close examination where the
differences caused by ext_paletted_texture is coming from.
