This one is not harmful, but might need fixing at some point.
The Cmd-Ctrl-3 and Cmd-Ctrl-4 keys are standard shortcuts for taking screen grabs in OS X.
Utilizing them in a certain position in Fusion 360 has the unwanted effect of minimizing the 'offset plane' to hardly visible size. This only happens if the source for the plane is the coordinate plane, not i.e. if an edge of a box is being offset.
Steps:
1. Construct > Offset Plane.
Pick one of the coordinate planes and start dragging it.
2. Press Cmd + Ctrl keys (together), and release them.
Expected:
This should have no relevance to Fusion 360.
Actual:
The offset plane is minimized to really, really small size (but continues to work).
Notice that during the Cmd + Ctrl press (or i.e. taking a screenshot) the offset plane disappears. I needed to use the Capture tool to get the screenshots because of this. It's probably due to the application losing keyboard focus or something. This is fine: the offset plane is an interactive element and interactive elements can be hidden if the application is not topmost.
