Not sure if this has always been this way but used Grab today on my 2015 rMBP and the quality of the grab was pretty poor. Previously on my iMac running 10.10 the grab would look identical to the screen, no artifacts. Can someone confirm/test this?
Grab on Yosemite saves in Retina resolution, as well as the keyboard shortcuts, so it's probably a bug.Yea same issue I'm seeing. Does this happen in Yosemite, I don't think it did? But yea it looks rubbish.. I'll log on feedback.
