OK! Thanks! I'll try it soon.

Thank you for reporting this issue.
As a temporary solution, adding `GRUB_FORCE_EFI_ALL_VIDEO=1` to the
grub configuration file and then rebuilding the grub.cfg file should
resolve the problem.
I spent some time investigating the background of this issue and found
it quite interesting.
First, an issue was discovered on an x86_64 Debian system and reported
to the QEMU community: https://gitlab.com/qemu-project/qemu/-/issues/2562
Qemu project said this is not their bug, so the bug was reported to
the GRUB community: https://savannah.gnu.org/bugs/index.php?66200
Then, GRUB fixed the issue:
https://gitweb.git.savannah.gnu.org/gitweb/?p=grub.git;a=commitdiff;h=ea0b76dc4a003f2b7f828ef0c24cc8227148b2f8
It was this commit that introduced the new bug. I believe that efi_uga
has been replaced by efi_gop[1] and should not be added back; if it
must be added, it should be limited to i386_efi and x86_64_efi[2], so
the grub community needs to fix this issue again.
