Thank you for the report; we have identified and fixed one bug related to your earlier screenshot, and we’ll investigate why your latter screenshot is possible.
Can I ask whether the class icons are appearing that pixellated in game for you, or if that quality loss is occuring after the screenshot was taken? I haven’t been able to reproduce that.
Thanks!
That shouldn’t be necessary; I’ll see what we can do about preventing that in future. Even integrated graphics should be able to display the class icons without too much worry. 
We believe all variants of this will be resolved in our next patch.
As an aside, the class art becoming pixelated should be resolved in our next update.
We have identified an additional bug which can facilitate illegitimate respecs. This bug won’t be fixed in Patch 0.7.3b, but a fix for it will be included in our next update.
