           Summary: OpenGL rendering on wrong part of virtual desktop if
                    window gets moved
           Product: Wine
           Version: 1.1.39
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown

This is probably a minor issue, but maybe it fixes a bigger bug.

I'm using wine 1.1.39 with default settings on ubuntu 9.10 with wine virtual
desktop enabled.

I downloaded a sample program from http://www.songho.ca/opengl/gl_fbo.html
(fbo.zip direct link: http://www.songho.ca/opengl/files/fbo.zip).

In the archive file there are sources and executable. If you run the executable
on ubuntu this happens:

program runs without problems, but when you move the window inside which cube
is rendered, it starts rendering outside of the window on the virtual desktop -
on the position where the window was before.


What should happen:

If you move the window while running the program in Windows vista 32bit home
the window moves correctly and nothing is wrong with rendering after that.
