Developing an MDI application (MFC based) with several child windows utilizing open gl at the same time, we have come across a lot of difficulties where on various machines (with only average video cards) have weird behavior.
The scene is only rendered correctly in one window, the others are just filled with the background and any 2D text we stuck on.
The application crashes
Redraw issues to do with the cursor over the window
There are tonnes of others. This has been tried on all flavors of windows, with the latest service packs, etc.
Any ideas would be appreciated! Especially if anyone is aware of particular areas of open gl which are notable for buggy implementations.
