Can CT fuzzing report which screen was active when a fuzz error occurs?

[samreid]

For sims with many different kinds of screens, it would be very useful for CT to report which screen had the failure. Would this be easy/difficult? Would there be false positives?

Assigning to @jonathanolson for initial discussion.

This didn't work as I expected it to, so I'll have to do some more research:
