Hey thanks for the feedback! A friend of mine was playing the linux version yesterady and sadly he encountered the same bug, which didn't occur nor on windows or browser which were the only ones I playtested thoroughly.
We found out that it's probably caused by the GPUPartiles3D rotation during mutating so a clunky workaround would be to not move during mutating. Could you tell me if it was the linux build you played? I might take it down and let linux players play in browser until the end of jam instead.
