I have created an ActiveX control that uses OpenGL to draw within it's window. It is hosted in a web page with additional HTML. During scrolling actions of the parent window, the control appears to overwrite it's bounds (overlaps the HTML).
I thought at first it might be the control trying to draw outside it's window but after watching events like WM_WINDOWPOSCHANG[ING|ED] and WM_MOVE, it almost appears to be an issue with how IE is performing it's scrolling (I've verified that we have not performed any OpenGL calls until after the scroll is complete).
Anybody seen this before, or have any suggestions?
I've tried some ugly hacks like forcing Window Updates of the screen after the scroll but of course it gives me an ugly flicker.
Thanks.
