Problem with username in GDM

Os. Fedora 34
After change gnome to version 40 i have problem with display usernames in GDM.
I see 2-3 symbols of username and after dotted .
Here is photo of problem:

I think this problem from Russian Fedora.
In Fedora 30, I moved from Russian Fedora to Fedora 30, but shablon of GDM remained from Russian Fedora.
If I remove all files from /var/lib/gdm/ Fedora 34 reinstall new good shablons?

So, How can i return default theme for GDM?

I removed all old rpm packets gnome*fc29
