What can be done with WPF to break the user interface?

Question

To my disappointment, I found out that one of the applications I'm working on has a bad effect on certain computers. Static graphics and user interface text suffer from a serious tear case without any animations. This makes the text unreadable and, of course, the graphics look bad.

I noticed this problem on different computers, but the one that really made me think was the new Toshiba laptop with the Radeon Mobility graphics card: when this laptop is running on battery power, there are no gaps - but when it starts, there’s a mess around. So this seems like a power noise problem that seems to affect the graphics card - I assume hardware accelerated graphics. However, graphics other than WPF look like you tell users: "This is not my application, this is your power source!" ?!

Have you ever come across this? Still fix it?

The application is .NET 4.0, and Windows 7 runs on the laptop.

regedit DWORD "1", WPF:

In the past, I found that on low-performance machines (netbooks and integrated graphics machines) this can often significantly improve the performance of WPF applications, as this reduces the memory conflict between the GPU and the CPU.
