Short description of error
Auto Depth (Preferences > Navigation > Orbit & Pan) makes zooming & orbiting slow while the Viewport Shading is "Material Preview".
It doesn't happen if Viewport Shading is "SOLID".
Exact steps for others to reproduce the error
- Open a scene with several objects (with materials applied onto them)
- Make sure to have "Auto Depth" unchecked in Preferences > Navigation > Orbit & Pan
- Try point #4 with "SOLID" then with "MATERIAL PREVIEW" viewport shading:
- Zoom and orbit the view
- You should not notice any slowdown, no lag
Now redo the steps #1 to #4 with "Auto Depth" checked (enabled).
Switching the viewport shading to "MATERIAL PREVIEW" makes orbitting and zooming sluggish, you should notice a lag.
