    Ever since I updated to High Sierra I've had tons of video problems that include black screens and flickering menus. I disabled DirectX and now everything looks like crap.

    I made a video showing what's going on. https://www.dropbox.com/s/9wbyc0g5hbe4l92/2015.mov?dl=0

    It does it when using 'Best for Retina display' and 'Best for external displays'. I'm currently using my macbook display and two external displays.

    I'm also uploading a screenshot of my Graphics settings in Parallels.

    I can confirm this did not fix the problem.

    Please take a snapshot, shut down Windows, select the option 'Scaled' (just for test purposes - this option may make you compromise on video quality in Windows) in virtual machine configuration under Hardware -> Graphics -> Resolution, enable 'DirectX 10', close the window and start up Windows. Let us know if the issue persists.
