Hello everyone!
First of all, thank you very much for the video. I have reviewed it and that is indeed strange behaviour.
Just before I report this issue I would like to gather 1 more piece of information, as we may struggle to reproduce this in a testing environment.
Can you please list your computer's hardware components? I'd like to check the game's minimum requirements are met and there's no bottle neck causing this to happen.

Thank you!
