I haven't checked yet. But...
Dmitrii, could you please check if something changes when you set
baud-rate? I can't see flickering in alacritty, when I
(setq baud-rate 1000000)
I do not know what it does, but it does help.
I mean, it fixes the problem with flickering completely.
Could you please elaborate a bit more about possible consequences of that?
but it's kind of hard to reproduce anyway for me.
