Well, I'll chime in with a weird bug that was supposedly gone from previous versions but came back in WP 5.4 Gutenberg.
You know those side panels where you can change values for blocks like padding, etc.? Well, every time I started typing in a value, the input field would lose focus. So if I wanted to enter 100 as a value for height in pixels, I would need to enter 1, click back in the field, enter 0, click back in the field, enter 0 again. Or type it in a text edit and copy-paste.

Googling told me it was a bug that had crept back: https://github.com/WordPress/gutenberg/issues/20950
It was fixed again in WP 5.5, but it was agonising working on layouts before that.
