Bug - Roughen Edges doesn't work the same in 2020 as it does in previous versions
In AE CC 2020, the Roughen Edges effect still shows the original edges of shapes and vectors. It also produces oddly colored edges.
This wasn't the case before this version. It used to produce nice rough edges.

I'm having the same problem - it is specific to version 17.0.0
Thank you for the bug report. We've reproduced this issue in-house and are working on a fix.
I'm getting similar results as OP. Black edges in parts where roughen is at peak
Yep seems broken to me. The roughened edges won't spread outside of the shape boundaries for me. And adjusting the paths give similar results to OP
