I recently upgraded my PC to a AM5 motherboard. My system runs KDE neon with full disk encryption.

I'm now facing the issue that when I want to enter my password in GRUB, each normal key press on my keyboard prints at least 5-10 letters on the screen. So if my password were "password", it would look like "ppppppaaaaaasssssssssssswwwww..." and so on. I need at least 5 attempts with very quick reflexes to only press each key only once for a split second. It's very annoying but once I make it past GRUB, everything works normally.

From what I've read so far the issue seems to have something to do with the USB port that the keyboard is plugged into and people seem to have fixed it by switching to a 2.0 port instead of a 3.0 port. My motherboard only has 3.0 and 3.2 ports though, so I was wondering if there is any way to change the "refresh rate" in GRUB, so to speak. Any help or advice would be greatly appreciated!
