Vignette causes crash

Same issue here. Getting tired of premiere not being able to handle things that a phone could even do... If I didn't use it for my fulltime work, I would 100% take the time to learn a new editor. 

Having this exact issue. I can change the amount, but the second I move the "midpoint" slider down too far it's an immidiate black screen. Only fix is to either restart the project, or switch to non-gpu rendering. 

How'd they mess that up. 

Seems to be a known issue.

Adobe is trying to fix this in the beta.
