Blackout Bug and Half Missing Skill Descriptions

It’s only happened to me twice, but as I was just flying around, everything turned black except for the UI. To fix it, I alt+tab and bring it back up. I’m not sure what causes it.

Many times the descrption of a skill (on the right hand panel) is half cut off because the description box isn’t big enough. As far as I know, you can’t expand it. Is that being worked on?
