Strange colored Lines and flickering when simulating since Nightly Build 30694 for Max

[Guest]

Hi there,
I downloaded the Nightliy Build "phoenixFD_adv_43001_max2021_vray5_x64_30694" since then i got very strange Behaviour when simulating. You can see in the attached Picture what i mean. The Viewport of Max is flickering and very often these colred Lines or different colored Grids pop up. Can you tell what this is? Cheers.

Yes indeed, there are some issues with the Simulator box in 3ds Max's viewport in the latest nightlies. Better revert to a slightly older nightly, such as 30676.

Cheers!
