Mouse Icon Distorted on Secondary Display
The problem is unfortunately an old bug with ATI cards under some multi-monitor setups that is being reported since at least 2009. I experienced it with an HD 4770. It was particularly recurring when I would host a virtual machine in fullscreen mode on my secondary monitor. But would also happen without it when I moved between screens. Just not so often.
There's no known fix at this time, Nathan. There's however a workaround:
If you enable mouse pointer trails, the corruption will go away.
- In your Windows 7 go to
Control Panel -> Mouse -> Pointer Options Tab - Enable Pointer Trails.
- If you don't like the effect, move the slider all the way to the left. This will make the trailing effect all but disappear.
That's it. The mouse corruption will "not" happen again. The constant redrawing of the mouse trails is effectively hiding the bug from view.
I'll add my workaround to the mix here, since they all suck a little. I've fixed the problem each time by moving the mouse to the top-right or bottom-right corner of the screen. I think by getting the mouse completely off screen, it's forcing the problem to resolve itself.
I'm using Windows 8.1 and have an AMD 7870.
