The problem is with the high DPI scaling, you can kind of fix this by going to the CursorFX.exe 's properties and going to the compatibility tab. Click Change high DPI settings and then at High DPI scaling override click the tick box for "Override high DPI scaling behavior. Scaling performed by" and then select System from the drop down menu and click apply. Relaunch CursorFX and it should be "fixed"
Clearly the real problem is CursorFX interfering with Windows built in scaling across monitors.
Which defeats the purpose of the selling point "NEW! High DPI support"
I am really disappointed with Stardock. It has been almost 5 months now and no update or info.
At least I kind of fixed this issue myself, but I would still like an official fix.
This however doesn't solve the cursor flickering issue I have
Edit Well over a year now, issue still not resolved:
I see you guys removed "NEW! High DPI support" from the product page instead of fixing the issue.
