Hello Jin,

I was unable to reproduce the issue you are experiencing. I have a couple of questions to help narrow down the issue you are experiencing.

  1. Does this issue happen in all 4.16.1 projects?
  2. Does the flickering occur for you under specific conditions?
  3. Was this issue present for you in 4.16.0?

Thanks!
