I have one of the retina display macbooks. Maybe this is an issue? Any image I import, regardless of its resolution is getting pixilated. Didn't do this before. Didn't tweak any settings. I'm lost. I'm running the software on a non-retina display desktop and everything's fine. On the macbook, this is what I'm getting, all chunky monkey blah:
I've tried a reainstall twice. Any help or advice would be grand. Thanks!
First try resetting the prefs. Quit the editor, then restart it while holding command+shift+option. Keep the keys down till you see a window asking if you want to delete the settings file. You do.
I would also check your retina display settings and see if anything's changed.
I don't have a retina display on a mac, but there must be some settings to tell the display what to do with applications that don't support retina displays.
Another thing i notice from your screenshot is the anti-alias setting in the tool options bar appears to be off which can cause the text to be even more pixelated.
