I am running my MacBook Pro (retina) with the Plugable USB Dock (single monitor) to a Samsung screen. However, regardless of which browser I use, when I open a window and then use the mouse to drag it elsewhere on the screen, a number of replicated ‘stacked’ identical windows and fragments of that window appear. I can only get rid of these by doing a page refresh. Very frustrating but the problem may be with me and some configuration mishap. HELP PLEASE!
My first thought is hardware acceleration. Please turn it this feature off in all your browsers, reboot and see if this makes a difference. Please also be sure you are running the most up to date DisplayLink driver (version 2.5) -> http://www.displaylink.com/downloads/….
