Keystrokes being read multiple times randomly in bootloader

[ristein]

Expected behavior

Typing password in veracrypt bootloader should succeed as always.

Observed behavior

Last boot I received wrong password error twice before success. This boot again the same until I mentioned it detecting multiple characters when I press a key once randomly, about every fifth keystroke. I had to be extra careful to detect it every time and use Backspace in case. But this was hard to do, especially when more than two stars appeared on one keystroke. One time it even received return twice and after failing password check it already skipped password input field and "PIM:" was already selected.

Steps to reproduce

I installed veracrypt 1.25.9 a long time ago and updated to 1.26.7 upon notification several month ago. Problem just started now. Can this be a sign of an attack? (Not that I would expect one, I'm just that normal guy acting paranoid)
