--- Comment #10 from Roman m01brv@mail.ru 2011-07-08 04:04:36 CDT --- I have some extra info. I use in my DeusEx a more modern D3D9 driver then its default D3D (seemingly 7th) and the D3D9 section in the settings file DeusEx.ini contains the following line:
BufferTileQuads=True
If I set this to False, the bug is largerly suppressed (although not completely eliminated). Now there is no corruption of the text inside the Load dialog, but the whole screen still gets corrupted for a few seconds. Apparently this occures when the green blurred "Ion Storm" logo is moving behind the dialog window (it's part of the starting animation). When it moves away, the corruptions go away too.
Maybe, there is another D3D9 setting that can remove the rest of the corruptions.
When I use the standard D3D driver, the bug seem not to occur.
