Hi - that is a weird problem. I'm not really sure at this point what could be causing it.
Does it only occur in portrait mode?
Does it happen on a vanilla Ubuntu system without the Intel stack installed?
It would probably be worth filing a bug with Ubuntu - even if it is an upgraded
component fronm the Intel stack at fault, they might be able to easily identify
which component it is (I can't think of any offhand which would cause this
behaviour), and if it's not then they'd be the right people to file a bug with anyway.
Installer 1.0.7
Ubuntu 14.04
Seems to work fine in landscape, but once I change to portrait and reboot, I'm seeing a strange issue with the fonts being off and difficult/impossible to read.
