Aero and ATI Catalyst?
Hi all,
I recently changed my gfx card from a 7900GS to a HD 4870. However, one annoying problem I have been experiencing is with regards to Aero on Windows 7.
I noticed that when running certain programs, such as Firefox in particular, sometimes when I try to click a dropdown box or just access a menu very quickly, before the menu appears, there is a black thing appearing behind it for a split second, before it finally appears (i.e. something similar when you try to resize the services.msc window). This is especially apparent when I am multitasking, perhaps due to lag.
However, I did not get this problem with my 7900 GS before. I tried a reformat already but no use.
Today, I decided to install Windows Vista on another separate hard disk. I noticed that this problem does not occur in Vista.
I am using Catalyst 9.9 on both Vista and Win7. However, the problems with Aero only occurs on Windows 7 but not on Vista.
Does anyone have the same problem with ATI cards as well? Is this a driver issue due to the WDDM 1.1 model used in Win7 for Aero?
