Public bug reported:
I have a new Intel DZ77BH-55K motherboard with an i5-2400 processor with
on-chip HD graphics. The motherboard has one HDMI and one DisplayPort
output. For testing reasons and on the search to solve the problem I
have connected both outputs to my EIZO EV2333W 23-inch 1920x1080 (16:9)
monitor (HDMI to DVI via adapter, DisplayPort to DisplayPort), but I
have the same problem when the DisplayPort cable is not connected.
The problem is that when typing more or less one of 20 keystrokes gets
ignored, leading to missing characters in the typed text.
