This is a trace of the variables used to create the glDrawPixels call:

trace:d3d_surface:flush_to_framebuffer_drawpixels right 0, left 0, bottom 0, 
top 0, mem 0x5db0040, bpp 4, pitch 6400

I assume GL is complaining because the rectangle passed to it has a size of 

Adding a simple right>left and bottom>top condition at least resolves this 
error. However, whether that is correctly emulating D3D behavior, I don't
