If I use a clipping plane the status bar vanishes. View menu -> clipping plane -> poof goes the status bar. The way I get it back is to drag the Windows task bar to the side (from the bottom default position) and then drag it back to the bottom. The task bar is not obscuring the status bar. If I drag the task bar to the side and enable a clipping plane the status bar still vanishes. Dragging the task bar back to the bottom still works to get the status bar back.

In the view menu the status bar is always checked, so it's not being unchecked / disabled by opening the clipping plane, it's just not being shown.

This could be a Qt bug, a FreeCAD bug, or possibly a Windows bug.

I tested this also in Ubuntu (in a virtual box virtual machine running ubuntu 20.04 as a guest, windows 10 host). There the status bar disappears when opening clipping plane and reappears after closing the clipping plane.

No problems with maximized window here:

My guess is that it's a problem of Y geometry. As clipping plane dock panel appears, it has a (quite significant) minimum Y size and it forces main window to increase vertically, pushing the status bar out of the visible area of the screen.

What happens if you set the clipping plane dialog floating, then maximize again the window ?

[TheMarkster]

Restore, Maximize, returns the status bar whether the clipping panel is docked or floating.

But at least this is more convenient than dragging the task bar around.

I have discovered when changing my display settings from 125% back to 100% the problem disappears. This is in Settings -> Ease of access -> Make everything bigger on Windows 10. The only problem with this is everything is smaller than I would prefer, icons, text, etc. (But the 3D view remains unchanged, apparently.)

I think I prefer dealing with losing the status bar rather than going back to the smaller icons/text.
