Some apps are rendered basically unusable by flickering (more accurately just disappearing) when I move the mouse over certain portions of the screen. Specifically I'm running into this using PowerBI desktop. When I hover over a chart or datasets, the areas under the cursor disappear. This is on a 2016 MBP 15 w/ TB. Steps I've already tried: Uninstalling/reinstalling the app Upping the Video mem to 1GB Disabling 3D Acceleration or using DX9 (these not only don't fix the issue but slow down the VM to unusable levels) Adding the flag video.hw_pointer=0 to boot flags Re-installing Parallels Tools Different resolutions And the problem remains. Firefox experiences some different anomalies where everything will appear as if highlighted even if I haven't done anything, and will also have sections disappear when hovered over. Any help is greatly appreciated.
