I'm running Windows 10 and Deskscapes
Deskscapes is working fine on my PC
with all High Contrast filters and all 4 high contrasts 1-4
I just updated Win 10 yesterday to latest version maybe you
should check and see if you have the latest version.
try purging and reinstalling Deskscapes https://forums.stardock.com/485954/deskscapes-support-faq#reinstalling
