Button click area is shifted left of icon #681
Description
System information
SolveSpace version: 3.0~bb56daf3
Operating system: Windows 10
Expected behavior
Clicking Occluded Lines button must switch mode
Actual behavior
The right side of the button is non-operate, no hovering or clicking events do nothing.
Seems the hover-and-click area is shifted left (see attached pic)
Solid model buttons are shifted too, but less. I think the width of spacers are not calculated right.
