Just upgraded from 3.0.7 to 3.5.4.
Previously if I wanted a widget anchored bottom right, I change anchor type to Unified, set Left and Right to Right, Bottom and Top to Bottom and zero out the offsets. That placed the zero point of my widget in the bottom right corner (shown aligned with the purple line corner). I'd then add elements to that widget that make up my bottom right UI.
But now, changing anchoring as above, shows it offset from the corner, changes the size of the widget and offsets X and Y. Looks like screenshot included. Is this a bug or have I missed something?
