Blocks/entities overlap HUD, blocks cursor, etc

Blocks that are highlighted (not using outline mode) and entity shadows (such as from dropped blocks, etc) overlap portions of the UI, making it difficult to play.

See attached screenshots:

Example of block overlapping cursor. Angled in such a way to show how only the highlighted block overlaps; in practice, the entire cursor is usually blocked while building

Example of block fully overlapping cursor and overlapping health.

Example of entity shadow overlapping health and the durability bar of the pickaxe. However, note that the highlighted block is no longer overlapping UI elements, since I switched it to outline mode. Regardless, the problem persists with various entities

This bug is making it very difficult to play, especially with the cursor being blocked. Most of the time, the cursor is fully blocked, making block placing (especially stairs) a nightmare. The solution so far is to enable block outlines, but I have vision problems and the outlines are almost impossible for me to see.

I am not using any texture or resource packs. The issue persists in any world, whether single player or realms. No graphical settings I've tried make it fully go away. Graphics are at all default settings for screenshots. I have tried reinstalling Minecraft from the Nintendo eShop to no avail.
