I understand, but if I were you, I would certainly not wait for the next Gamestudio update. I would just finish my project without draw_quad.

It's on my list, but I can not quickly produce an update for you. Draw_quad is the central panel drawing function and used at about 50 places in the code. Panels are early clipped at screen corners for speeding up 2D games. And there are internal functions that use draw_quad with a render target and also rely on screen clipping. Anything that affects existing projects in this way must be carefully implemented and tested, it's not done in half an hour.

I must also admit that the problem seemed not really urgent to me. Sure, you can not use draw_quad for your purpose, but there are tons of other draw functions. Can't you instead use draw_obj with a bmap object, or even just call a D3D draw primitive?
