Wow - that's very strange. I'm really sorry this happened to you, as it didn't occur on any of the systems we tested it on. We're going to take the patch offline for the moment until we figure out what's going on.

To help you further - could you please let me know if deleting your graphicoptions.xml file helps.

Go to C:/Users/[usename]/AppData/Local/Divinity 2/Profile
Delete the "graphicoptions.xml" file
