My computer has started displaying all WPF apps blurry - not just text, but borders have misplaced pixels as well. For example, the right border of a certain textbox is one pixel to the left of where it should be. Resizing or moving the window has no effect.
I was able to fix this in Visual Studio by disabling hardware-accelerated rendering, but the problem still occurs in other apps that use WPF. Applications that don't use WPF are fine.
Changing ClearType settings have no effect.
The only other issue I could see, is that the diagnostics of the DirectX tests showing a spinning cube, ran really fast -- it was almost impossible to see the spinning of the cube. Disabling AGP Texture Acceleration slowed down the spinning, but now it spins much more slowly than I remember before this problem arose. But changing this has no effect on the original issue.
I am running Windows XP SP3 on an Acer Aspire 5050. Graphics card is ATI Radeon Xpress 1100.
DirectX version: 9.0c (4.09.0000.0904).
