I think Stefan said something about this not being correct. The blitting is 
going into the render target not the current surface. In your case if the 
surface is not the render target, then it's not being properly selected.

Was it about blitting in general or surface_blt_to_drawable? Note that 
this routine isn't for blitting in the usual gdi or directx sense (as in 
from one bitmap or surface to another) - that code is in BltOverride. 
surface_blt_to_drawable is helper function for 
LoadLocation(...,INDRAWABLE,...) - which isn't supposed to be called for 
regular textures or offscreenplain surfaces.

My comment was about the read-from-drawable code, this is writing to the 
drawable. The patch is correct as far as I can see.

(The patch that I said was wrong was doing about the opposite in the 
drawable->texture copy path)

Ok fair enough. Thank you for explanation.
