In New file turn on shadows in Solid draw mode.
Add plane and scale it outside viewport clipping area
You will see shadow glitch like this:

Thanks Michael. :)
To the developers: but in the file not only one shadow bug, but a couple another related too, I think. So check the file definitely

I can confirm, it seems to be related to the scale of the objects.

Hmmm there was already a report for this issue. But cannot find it. It is a known issue, but don't think it will be tackled in the short term so I will set it to known issue.

In this scene something similar happens. Confirmed on Win10 with Blender 2.83.10 / 2.91.2, and on Win7 with Blenders: 2.83.10, 2.91.2, 2.92.0-213f8294b5c8 beta, 2.93.0-92b0803f35a7 alpha.

The glitch is seen on few frames here. And only in Solid viewport shading. It hides - if any 1 of 3 modifiers: Bevel, Array, Curve are disabled. And it disappears - when moving object, sometimes reappearing on other frame(s).
