I can confirm this bug with version 2.02~beta2.

My screen resolution is 1680×1050 with an NVIDIA GPU. The input delay is around one second on each key press.

You can Google around, there are plenty of threads on various forums raising this issue: https://www.google.com/search?q=grub+2+input+delay

Version: 2.02_beta2-r7 : 2 (Gentoo), but bug has been present since I switched to Grub2 a couple of years ago.

If Grub is configured to run at a higher resolution (1280x1024 or 1600x1200) the menu has a user input delay of several seconds. I have 6-8 entries in the menu, and if I press arrow down, the UI takes a couple of seconds before moving to the next entry.

My machine is an Intel Core i7@3.2 GHz with 16 Gb of RAM and an ATI Radeon R290, so the hardware should not be a problem.

I use two screen connected via DVI connections.

I currently don't have access to my computer, so I'm unable to paste my grub.conf.

This issue has been reported on many, many forums before, but there never seem to be any other solution than "If you revert to running it in 640x480 it's faster".

I really hope it is possible to improve the performance for the higher resolution as well.

Examples of bug reports:

I really hope this can be solved soon.
