Hadn't used my DisplayLink monitor in a few weeks, so don't know when this happened, but on Google Chrome Version 46.0.2490.6 dev (64-bit) the browser window gets visually corrupted when it's dragged onto a DisplayLink monitor.
Works fine with Hardware Acceleration turned off. Works fine when dragged back onto a non-DisplayLink device.
Probably more a chrome bug than DL bug but felt it worth reporting both places.
Mac OS X 10.10.5, DisplayLink Driver 2.4 (3 Jul 2015), Late 2013 15" rMBP, NVIDIA GeForce GT 750M
