Shadow is bit more correct in yesteday 4.3 build, but cube render is still bad.

The shadows appear correct here. There might be a missing refresh after initial compilation. Moving the light should fix it.

As for the cube itself, this is related to #123020. That is unfortunate but we cannot support the same setups as before with the current state of EEVEE.

Leaving it open for the missing refresh.
