Thanks for going through all that troubleshooting.
Did you install any special video or audio codecs or plug-ins? Have any computer security features other than antivirus and firewall(s)?
Are you working with a dual monitor system? Any school or company networks involved? Any special Windows High Contrast Theme?
I think the best plan right now is for you to explore and experiment with the idea of uninstalling most likely candidates for conflicting programs or 3rd party features.
I will keep thinking about this.
Best wishes
