Map view not filling window in ArcGIS Pro

[MatthewLaw]

Working in ArcGIS Pro, the map view seems to be locked in one aspect ratio, and when I resize the window the map view doesn't resize accordingly, but instead leaves bars at the top (if the view is too tall for the aspect ratio) or sides (if the view is too wide) – see attached screenshots for examples of both. Within the map area shown everything works as usual, although I think the display is a little blurrier than usual, but the bars do nothing. The screenshots show the case with a 3D scene, but it is the same for 2D maps. I have tried closing and reopening each of the views and the entire program, and gone through the settings but haven't been able to resolve the issue.

Hi Matthew, 

Looks like Animation is part of your workflow.  Perhaps the "Lock View Size" button (Animation tab on the ribbon under the Export group) is enabled?

Hope this helps, 

Tom

This did solve the issue, thank you!
