When zooming (for instance, with the zoom magnifying cursor), if I’m zooming in either in or out and then try to zoom in the other direction, the zoom percentage shown changes in the direction I was first zooming rather than in the new direction.
For example, I’m at 51%.
I click with the + magnifying glass and it zooms in and shows 74%.
I click with the + magnifying glass and it zooms in and shows 84%.
Then I click with the - magnifying glass (holding option) and it zooms out but shows 100%.
I click with the zoom out mag. glass again and it zooms out and shows 83%.
I’m not even sure if what is displayed is actually what it is but don’t have time to do measurements.
The same sort of problem happens with “Zoom to fit”.
