Hey All, So I just upgraded to the 344.48 drivers but found a weird problem on my rig. I have Dscaler 4.2.2 installed on my system. It is basically a TV watching software which uses the internal tv card on my machine to render television. Everything was working fine with the previous version 344.11 but ever since I installed 344.48, a weird problem occurs which I believe has something to do with the way these drivers render video on overlay. When I run Dscaler on the latest drivers, the program opens up choppy. Video is not properly shown in the Dscaler window. Menu half appears and doesn't appear. If I do an Alt+Tab or Window+D, then switch back to Dscaler, I am able to see the menus and video again. The colors also get a little distorted in the system tray. However, If I again switch to some other window and come back, the choppy UI returns! I uninstalled the drivers and went back to 344.11 and the problem is gone but wanted to know if someone could help suggest a fix. Seems to be a bug in the new drivers. Also, I am afraid it does not stay with the next batch of drivers and would like to get this fixed here only if possible. OS: Win 7 Ultimate SP1 64-bit BTW, I run Dscaler in XP SP3 Compatibility Mode but thats not an issue. This is actually required to access the volume and other settings which dont show up if I run in normal Windows 7 mode. I know its an old software but does the job well. Any help/suggestions would be appreciated.
