Looks more like a graphics card/driver issue. Try installing the lasted Microsoft certified graphics card driver for your system. You will need to know the make and model of graphics card and will need to get this from the card manufactures web-site.

 Did you ever resolve this issue? I have the same problem on my Dell Inspiron 15 7000 laptop, with Windows 8.1 (64-bit), Intel i7-4510U processor, and a Nvidia GeForce GT 750M graphics card. The drivers are always kept up-to-date, but nothing seems to solve the issue. The only way to make it disappear is to close and re-open Revit.
