Pointer goes invisible intermittently on non-DisplayLink 2nd monitor when using 2.0a2
 

So I think I've found another bug that can be attributed to the DisplayLink 2.0a2 driver. The cursor sometimes becomes invisible on my non-DisplayLink 2nd monitor that's attached through mini-DisplayPort.

I have an mid-2010 iMac 27" running 10.8.2 with three 27" external monitors in portrait mode. The second monitor is a Dell 2709 connected through on-board video through DisplayPort. The third and fourth monitors are Dell 2713s connected with DisplayLink connectors over DisplayPort over USB2.

This happens quite often in Safari running on the second monitor using on-board video. The pointer will disappear suddenly, and then it will only appear over a link when it changes to the hand icon. Clicking on the Safari window doesn't bring the pointer back. You have to click on another monitor to re-establish the pointer, and then it appears again on the 2nd monitor that's attached via on-board video.

Here's a video of what's happening. Pretty sure this is because of 2.0a2, because I didn't get it when I was using the 1.8 driver:
