I had this packages istalled (exported from F33)

Description of problem:
After clean system was installed. GRUB menu was working normally.
After installing the packages from the attachment, the font in the menu became small and you can see how the underscore character "_" runs line by line of the screen. Until "_" reaches the end of the screen, the menu does not respond to the keyboard. It tooks about 20-40 seconds. 


Version-Release number of selected component (if applicable):
grub2-common-2.06~rc1-3.fc34.noarch

How reproducible:
Got if first after 33->34 upgrade. Then installed clean F34 beta. After installation menu worked fine, then:
"dnf upgrade, 
dnf install $(cat ~/packages.lst),
akmods --force,
dracut --force"
Nvidia drivers were installed, but nouveau was not blacklisted at that time. 

Steps to Reproduce:
0. 4k screen.
1. Install F34.
2. Update (kernel-core-5.11.3-300.fc34.x86_64).
3. Install packages from attachments. 

Actual results:
Long GRUB menu drawing, unable to switch/select menu items for some time (less then minute)

Expected results:
Fast working menu.

How did you solve the issue? This seems to be a duplicate of bug #1946969.
