If you switch the "Render Method" from "Dithered" to "Blended" in the material settings of the cube, it kinda fixes it, right?
I guess the Dithered method has some issues...

Also, if you zoom in close to the cube, the light starts to show up, and the navigation gets really slow, right?

I can confirm the issue. It seems to be a recent regression.
I will try to find the commit that introduced this issue.

This to, but navigation at this zoom level is usually slow

That's an eevee next only issue actually.... you can try the other way around (scale the cube to almost the size of the viewport) and it will become very slow to navigate... no such issue with legacy or cycles...

It is hard to bisect on Windows due to builds that fail just when selecting EEVEE Next.

@mano-wii In some of those builds where selecting EEVEE Next crashes, starting blender with blender_debug_log.cmd makes EEVEE Next not crash... (again, some builds, not all of them)...

Can't replicate on my own, for me is smooth, don't see any lag

You're right... just downloaded the latest build and that scaling issue seems to be fixed...
