as already mentioned, I have some weird drawing issues.
It's pretty hard to reproduce and thus not always happening, still, I have been able to capture one.
This is how it looks like: http://video.ionic.de/iTerm-Drawing-Issue.mkv (and as you can see, selecting the text gets rid of the problem.)
Blur and transparency were enabled, though no clue whether it's related to this.
I have never used full screen mode as well.
