If this does nto fix it, please try setting your resolution to 16-bit and let us know if that fixes the issue.
Right click on desktop > screen resolution > advanced settings > list all modes > select 1680x1050 16-bit (60Hz)

You could also try rightclicking on the executable and setting compatibility mode.
Go to C:\Program Files (x86)\Steam\steamapps\common\divine_divinity > right click on div.exe and click properties > compatibility tab > check the box next to "run this program in compatibility mode" and try windows xp sp3.

If you still have the problem, please contact support@larian.com.
