Graphics Quality Degradation (After lock/unlock)

[RajaSS]

Hi,

I have a windowed mode graphics application which uses OpenGL and Directx3D. Though the quality of the graphics and text I have is very good intially, once I lock and unloack my system it goes for a toss. The Quality degrades. I can get back a better quality if I have a bigger window while locking and unlocking. But if I resize the quality degraded window to a bigger window, the quality is still worse.

Any pointers to what all messages that comes in while locking and unlocking the system? Any clue on the problem?
