The same behavior, consistent with what is shown in the video link below, is
evident in Heroes of Might & Magic 3 Complete, Might & Magic 8, Might & Magic
9. Note that Might & Magic 9 is a 3D game, even though the rest are all pretty
much 2D only.

This problem does NOT manifest itself in System Shock 2 from GOG.

In considering Might & Magic 9 vs. System Shock 2, I wonder if the bug only
manifests itself with older versions of DirectX.

Might & Magic 9 is from 2002 but uses LithTech 1.5 tech created sometime around
1998-99 (http://en.wikipedia.org/wiki/LithTech#1.5). This would imply that MM9
might be a DirectX 6 or 7 game. On an outside chance it could be DirectX 8.

System Shock 2 from GOG uses the NewDark engine, which, according to this link
(http://www.ttlg.com/forums/showthread.php?t=134733) requires DirectX 9.

In fact, some other Googling seems to show that games using the latest DirectX
9 (9.0c?), at least, don't have this flickering issue.

I think it would be a good idea to test games using DirectX 9.0b and down until
the problem first manifests itself. Then, as you work your way down DirectX
versions, the difference in what is happening between the last working game and
the first broken game might reveal the source of the bug.

Unfortunately, I'm not sure where to get a list of games broken down by the
DirectX tech that they use.
