Object disappears from canvas when panning, zooming, orbiting etc. from an orthographic camera position.

Is there an existing issue for this problem?

• [X] I have searched the existing issues

OrcaSlicer Version

2.0.0

Operating System (OS)

macOS

OS Version

14.2.1

Additional system information

MacBook Pro M3 Max, 48gb RAM

Printer

X1C

How to reproduce

1. Open 3d model
2. Press CMD+3 or CMD+4 to view model straight on
3. Attempt to zoom in or out using scroll wheel or even pan

Actual results

Anytime I try to adjust the view (pan, orbit, zoom in/out) while viewing my model from an orthographic position (CMD+1, CMD+2, etc.), it causes the model to completely disappear from the canvas. When it happens, it almost seems like I zoomed in too far. However, no amount of zooming out allows me to find the model again. I am forced to restart the program each time this happens.

Expected results

You should be able to simply zoom in to see the model closer up.

Same issue here. Has the cause been figured out?

Same on Windows 10. O-S 2.0b

Btw, this is the same with "perspective" view.

The problem also exists in the current version of Orca Slicer 2.0.0 (Win Final Version).

Set orthogonal view. Insert a primitive cube. Press Alt gr + 4 for the front view. And zoom in!

Everything disappears

Happens to me sometimes as well.

The user might accidentally move the objects outside the window as well and a function to re-center (View all, Zoom all...) the objects in the 3D window would be useful and solve the need for re-starting Orca every time this happens.
