Question about OpenGL/D3D

[Mike Schaadt]

Has anyone tested using standard window objects in a window that also had an
opengl/d3d context?

I believe Terragen 2 is attempting to do this.  If this hasn't been tested,
than it might be the cause of all of the static that appears non opengl
area, making the program nearly unusable.

No messages get printed to the console from wine(Terragen 2 prints out a
fair bit of debug info there, but nothing from wine that would cause the
problem, just a few warnings that shouldn't be related).

Any thoughts?

This is known not to work. It was a regression due to the window management 
rewrite.

The problem is that since the window management rewrite all window elements 
except the main window are not X11 windows. So the clipping done by X11 on 
opengl contexts does not work for subwindows in wine.

The current plan for fixing this is, I believe, to create an overlay window 
which is used for opengl drawing. The other idea was to set up the opengl 
scissor test, but that turned out not to work correctly, and we need a 
seperate window for antialiasing support too.

Ah so that was the infamous problem with things like the WC3 Map editor, and
such? Thinking about that not it makes sense.

Ah, alright, and I meant now instead of not. Me and my typos... always are
inconvenient. Anyway, thanks for the info!
