Similar problem here. External 27" monitor via docking station. When I have certain applications open, moving the mouse to the left hand border of the screen can make screen flicker and then eventually crash - white screen. 100% reproducible in 5 seconds. Only resolved by restart OR using surface keyboard open/close to sleep the device and reawaken it. The offending apps are Outlook, only with a full screen email message form open, Word and Excel. But not Powerpoint, OneNote or anything else in MS Office. Both Office 2013 and 2016. No other applications crash the monitor (tried with Skype, Notepad, Chrome, Acrobat, etc.). Tried different monitors, etc - still crashes. Its driving me nuts. Any suggestions appreciated.
By the way, I tried to upload a video of this happening, but the site doesnt allow mp4 attachments ...
