inhibit-redisplay appears to be t when miniframes are asked to resize.
Could that be related? I tried letting it to nil and that didn't help.
It also happens that setting the resize to happen via run-with-timer
fixes the flicker:
https://github.com/muffinmad/emacs-mini-frame/pull/32/files#diff-8289c4c5300044ca6d7f9f6f60067a1b5e0d61b6ad0b58720a7c694662ea13abR207
Unfortunately, that prevents resizing when displaying a prompt like
`yes-or-no-p`.
The other different thing about the minibuffer resizing is it all
happens within `read-from-minibuffer`
