In the past there were some 'linux' patches, dunno rly what they fix or w/e.
About the 1st msg, you use using a laptop with a dedicated video card, by default it's using it's default card, not dedicated, that's why you got the message :)
On my w8 and AMD video card I have a program where I can define which card should be used for X, Y program. Like this, I can chose high/low-performance - default, dedicated card.
About 2nd program, no idea, Maybe it's related to 1st one and that's why it's not displayed correctly. Or sort of 'missing font', that would be funny :D
