I'm using 22.04 with a Dell 34 inch ultrawide monitor (S3424DWC) connected to an NVIDIA 3080 by HDMI.
Here are all my installed GRUB versions (although probably unnecessary as they are all from the default 22.04 install):
ii grub-common 2.06-2ubuntu7.2 amd64 GRand Unified Bootloader (common files)ii grub-efi-amd64-bin 2.06-2ubuntu14.4 amd64 GRand Unified Bootloader, version 2 (EFI-AMD64 modules)ii grub-efi-amd64-signed 1.187.6+2.06-2ubuntu14.4 amd64 GRand Unified Bootloader, version 2 (EFI-AMD64 version, signed)ii grub-gfxpayload-lists 0.7 amd64 GRUB gfxpayload blacklistii grub-pc 2.06-2ubuntu7.2 amd64 GRand Unified Bootloader, version 2 (PC/BIOS version)ii grub-pc-bin 2.06-2ubuntu7.2 amd64 GRand Unified Bootloader, version 2 (PC/BIOS modules)ii grub2-common 2.06-2ubuntu7.2 amd64 GRand Unified Bootloader (common files for version 2)GRUB looks amazing in the default autodetected resolution (3440x1440x32) but is really unresponsive (1-2 seconds delay to select a different item) which makes it a bit unusable.
None of the other resolutions that are available with the GRUB videoinfo command are superwide and all look skewed on my display (but they do respond much faster).
Is there anything I can do to speed up GRUB at my monitor's native resolution? Or can I force a slightly lower (but non-skewed) option?
