How to fix font size issue on a clean install of Ubuntu 20.04?

Question

linux

Good morning.

Did a clean install of Ubuntu 20.04, languages ​​english (main) and Russian. After the first reboot, there is a problem with the font size: in applications, the font is standard (browser, file browsing ..), but in the top panel (date, settings), the list of applications and on the desktop, the font is very small. In Gnome Tweak Scaling factor is '1.00' , if you change the value and return '1.00' then the size becomes correct, but crashes again on reboot. When I tried to set the Scaling factor through the console, the effect is the same. Proprietary, native, Nvidia X server prog also installed firewood for vidyuhu, everything looks correct in it.
Who faced, please tell me how to fix

1. Screen slave. default tableshttps://prnt.sc/u3w3ca
2. Screenshot of the working table after changing the Scaling factor in Gnome Tweak (just changing the value, and returning to 1.00) https://prnt.sc/u3w3ut

UPD: the problem was in the video driver, when switching to the default (opened from nouveau), the font size became correct. Other proprietary packages except nvidia-driver-440 (430,390) simply do not become (on reboot it is on the Count of files, blocks.. line), perhaps this will be fixed in new versions of nvidia
