I tried that, doesn't make any difference. I'll do some tests outside wine
with glDrawPixels, because I'm not really sure if it's really tha

Does hardcoding the the coordinates to (0.0f, 0.0f)-(1.0f, 1.0f) make
any difference? Might be a quick way to rule out texture

Do I need to bind a texture? I create a new texture with glTexImage, upload a

OpenGL needs to know which texture you're operating on

Hello,
I'm trying to change IWineD3DSurface::UnlockRect for rendertargets to avoid
glDrawPixels. Instead, I'd like to load the image from memory into an OpenGL
texture, and draw that texture with a textured quad onto the front / back
buffer.
The problem I have is that the texture(or better, the
