"Show object while dragging" make rectangular objects disappear

Issue:

"Show object while dragging" make rectangular objects disappear

Solution:

This is GDI mode restriction.
Most TC tools use operation GDI XOR while dragging. See Wiki GDI XOR

It dramatically speeds up drawing, but if objects match (rectangle + selector box), then after operation objects become invisible.

I dont see the solution her, but thats maybe just me.
I do see an Issue and a Reason, but no Solution, unless the Solution is to read a wiki page i need to search for, maybe they could use a litte bit time and explain the solution here ??

I looked up "Wiki GDI XOR" and got a lot of nothing: Wikipedia XOR gate.

I'd say there is no solution.

Two workarounds:

1. Turn OFF Dragging options>Show object>Wireframe; or

2. Assign a nonzero Line Width to the object.
