This is very likely an unrelated issue to any kind of desktop hang 
you're seeing. The graphics fuzz shaders are the result of fuzzing to 
intentionally generate unusual control flow structures which are likely 
to trigger shader compiler bugs. Typical desktop workloads don't have 
such shaders, so any generic desktop hang you're seeing is almost 
certainly unrelated.

Cheers,
Nicolai
