Thank you for usefull hints. Unfortunatelly this is not the problem.
The way openGL works on X is it uses X window's context. That wasn't a problem
more then a year ago - when we had X window for each child window. Basicaly each
Wine's window was X window. That was causing lots of problems which were fixed
rewriting Wine's window management.
Main key point of that rewrite was "Creation of X windows for top level windows
only". So in other words, only outer most Wine window has a coresponding X window.

That's why when an app wants to draw something on Wine it does that for the
whole window. And ATM there are no "propper" ways to make it draw in a child
window only.
