The keyboard driver mixed up the key press/release events for the
special keys.
Patrick Georgi explained:
The |0x80 codes are "break codes", that means, codes that are emitted
when the key transitions from pressed to non-pressed, so the modifier
was always in the wrong state, as soon as you pressed shift for the
first time.
