Well, it's just garbage. Attached anyway.

When the "screen lock" password prompt screen starts it's completely garbled.
When I blind-type in the password, the desktop shows up and it looks kind of OK
until a new window is opened and then it looks like rectangular area full of
horizontal lines.

No, switching VTs back and forth doesn't help when this happens (it makes
things worse actually).

It's not 100% reproducible (but close to that on the IVB machine) and I've seen
it once on my other machine based on Sandy Bridge too.

Thanks,
Rafael
