Hello, I'm having an issue with some of the simulations I'm trying to run and having difficulty resolving it. I was hoping to reach out for help. 

The issue appears to be that when I use certain masks elements, I see bleed through in a particular region. An example is attached below. The masking element contains thin vertical stripes and I've attempted to test many variations on it but this seems to correlate with this bleed through effect in the lower left quadrant just after the masking step. If I use an identical mask without the vertical striping it looks as expected but the vertical striping is an important feature of the simulation.

Would love some direction or guidance towards eliminating this issue. I'm out of ideas.
