Strange bug while resizing window

I built a scene (under Win32). Then I begin to resize window. When windows reached some size two black bands appeared at the left and bottom side of the window. If I turn off double buffering (flag PFD_DOUBLEBUFFER) or use PFD_DRAW_TO_BITMAP - no bug.
What’s the matter?

Thanks in advance.

Hi !

A search on the forum archive should give you the answer… anyway, this is a bug in opengl32.dll (the software rendering library), not much you can do about it, unless you are using HW acceleration, in that case it might be something else…

…but unfortunately you can’t have hardware acceleration while using PFD_DRAW_TO_BITMAP
