May be, but this is so minor in general, that I barely care as long as it boots properly.
Way bigger annoyance is that grub still doesn't support luks2 and uses some gimped variant of libcrypto without proper hardware acceleration that decrypts boot volumes for almost a minute. That is way more serious than boot resolution annoyances.
In terms of material impact, it is minor but as far as impression shaping papercuts go, bootloader jank is pretty high up on the list.
What can I say? Feels weird to include a JSON library in a bootloader.
That's also a peeve of mine. Is there a way at all for grub to use hardware acceleration there? Or maybe the bootloader isn't allowed to do such things
