switch of language freezes keyboard

[Sergey Ivanov]

Hi there.
In my ubuntu 20.04 i have two input sources (en and ru) installed and switching between them via super+space is successful but freezes keyboard for about 2 seconds whatever editor i'm focused in. It happens not always, bu, say, in > 50% of input switches. The only thing i could distinguish it happens when i swith to english. BTW, english is a system language as well.
It never happens in ubuntu 19.04 and previous versions as well.
