dlumd11.dll and dlumd10.dll problems with another app.

[AlbanRampon]

Hello,

This could come from the game bypassing Windows desktop manager composer.
Some games try to talk directly to the graphics card to improve the performance when working on fullscreen.
Do you have the same issue when launching the game in windowed mode instead of fullscreen? In a window, the game must use the desktop composer to render the desktop.

Kind regards,
Alban
