This demonstrate a specific problem that may occur in Inkscape.
00:15 The issue...
01:43 Enabling "scale the stroke width with same proportion" doesn't help (because the rectangle stroke width does change on size - unwanted).
On posting, I realize that Obs studio on "window recording mode" doesn't show other settings - the erratically mouse movements on screen is caused by settings and properties window is hidden.
The video is also supposed to demonstrate
* For select path 00:33 - the Fill and Stroke dialog - the line width property haven't changed.
* Preferences - Behaviour - Transforms : Store transformation = Optimized
