Selection box shows up too late when zoomed in

Reproduction steps:

  • Switch to one of the orthographic views
  • Zoom in until you are unable to zoom in any further
  • Start clicking and dragging to create a selection box
  • The mouse will disappear and not show a selection box
  • Keep dragging
  • After dragging a little over 4 world space units the mouse will suddenly reappear and a selection box will be drawn
  • Notice that the selection box starts at the point the cursor reappeared, not the point you clicked down

Expected behaviour:

  • Cursor should not disappear
  • Selection box should immediately be drawn when you start dragging
  • Selection box start should not have an offset from location of initial click

Basically I expect it to behave the way it already behaves when zoomed out far enough.

My guess is that there is a small “deadzone” to separate regular clicks with minor movement from box selections. However, this distance seems to be calculated in worldspace instead of the more logical screenspace, which might cause these issues when working on a small scale.

Edit: tested in version 4.7.3
