This is a kernel problem that affects Dell laptops. It has been fixed
upstream by Matthew Garrett. The issue is that some keys on a Dell
laptop do not produce a key down, key up sequence when the button is
pressed, and instead just produce key down and NOT key up. This confuses
X greatly, as more and more keys are being pressed "together". This is
fixed in 61579ba83934d397a4fa2bb7372de9ae112587d5 on 15th August in
Linus' tree.

Input: atkbd - expand Latitude's force release quirk to other Dells
Dell laptops fail to send key up events for several of their special
keys. There's an existing quirk in the kernel to handle this, but it's
limited to the Latitude range. This patch extends it to cover all
portable Dells.
