I'm still setting up my MBP Retina, but noticed this weird thing. Raw photos work fine, but JPEGs show at half size in Adobe Bridge. If they are 1024 px wide they are shown at 512 px. I can't seem to find a setting for this, might it be a bug?
Tried at different display resolution scalings. Using Bridge CC (18.104.22.168).
This first screenshot is on my 24" 1920x1200 monitor.
This second is on my laptop retina screen.
