Since I updated my video drivers, sometimes text and lines on the screen don't appear quite right. Everything looks fine with default drivers that come with Windows, but I had to update the drivers due to errors when using VirtualBox.
The symptom comes and goes. It's hard to tell what exactly triggers it, and what clears it is also somewhat unpredictable. Sometimes it will clear up when I choose another window, change the zoom level, or scroll within the same window. Sometimes it seems none of these work.
The system is an HP EliteBook 8530p with ATI Mobility Radeon HD 3650 graphics. OS is Windows Ultimate x64. Below is an example screenshot showing the text distortion even as I write this post.
What could be causing this? I used AMD's detection tool to confirm I'd downloaded the right driver. Is there some advanced setting I need to tweak that might just not be right for my system?
