Hey! do you mind sharing a repro in a PG?


“PG” here means Playground. To create a repro, go to, recreate the bug inside the playground, then hit the save button and share the link with us :slight_smile:

Hey there, I was really curious why this code wouldn’t work and I went ahead and made a quick playground that runs your code when the box mesh is clicked and it seems to be working. You can see below that I used an ActionManager to respond to clicks on the mesh. :slightly_smiling_face: :beers:

EDIT: I tried this playground repo out on version 4.2 and it does produce the flickering behavior, so I suppose it’s been fixed already. I recommend to try using the latest preview build and see if it fixes the issue for you. :slightly_smiling_face:

Yes this was a bug in 4.2 which was fixed in this PR:

Like Blake has suggested, make sure you are on the latest version 5.0 preview. If there are still issues of this please let me know with a repro and I will definitely take a look!
