Yes. Exactly.

On which level? As you can see from the screenshot, the cursor is always
left after SPC. Just after SPC you see two cyan boxes. One is always on,
second one is blinking. I can also sometimes reproduce it in other
modes/situations. Once, I was only browsing through C file, and it
happened after Down.

My theory of this is (please take this as it is, I do not know new display
engine to details): the problem is connected with blink-cursor-mode and
redisplay. I think that the desired matrix is not compared correctly with
the current matrix (so the old cursor is not cleared).
