I'm running Windows 8 and have a simple demo project which includes Cef. When starting up Dropbox in Cef I get a blurry screen as shown in the screenshot attached. I've also included the preferences from Display settings in Control Panel.

I have NVidia graphic card and have NVIDIA Control Panel running, but cannot find any specific settings which should affect this, but I'm no graphics geek. The sample project can be attached if needed.

Running dropbox.com from Windows Forms gives no issues with regards to the display.
