Hey there! That also happens with NVidia GPUs, using a GTX 1700 here.

Hmm that is weird, thanks for reporting.
Does it also happen in the WebGL build? And I assume you are in the second reality when it happens?
Nvidia 30x0 series seem to be fine. I wonder if this is some undefined behavior inside a shader. Have to investigate this on a affected system.
Thanks for investigating it.
