Weird issues when moving app windows around on Mac OSX Yosemite
 

I jus got an AOC 1659W monitor and am using Mac OS X El Capitan. I downloaded and installed the latest driver that I found online so I think I have the most recent driver.

In many applications, when I move the app window around it does this weird "tiling" effect where it like re-draws part of the app window within itself a number of times. Often I have to minimize the app window and re-maximize it to get it to display normally again. Needless to say, this is quite inconvenient and makes the monitor barely usable.

I'm wondering if anyone else has had a similar issue and if there is any workaround?
