Can confirm. The smaller the shadow distance and the higher the shadowmap resolution, the more noticeable the effect becomes.

Here's another example:

There's also another weird effect with the Sun reflection:

Hello, at the moment, there isn't really a fix for the spots. As of now, you can only fix it via adjusting the shadow distance and shadow resolution. Preferably, the shadow distance should be the same as the render distance in blocks and adjust the shadow resolution only when necessary.
