Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
To start with, Ive installed x6 on windows 10.. It can be made to run, and to run reliably.. With that being said, The gausian shadow / blur is accessed a bit differently in x8.
If you get stuck or have further questions or want to discuss reinstall x6, let me know!
I strive to provide great service, and greatly appreciate a 5 star rating clicked and submitted when you are satisfied.. I always answer follow up questions.Dustin S.Senior Technician and Network Switching Systems Operator / Maintainer.
