one touch disappears when approaching to another

Hello again!
i got a problem with controlling two objects at the same time with touches
when I bring these points to each other, one touch disappears
is it possible to fix it somehow?
there seems to be no errors in the code itself, I can briefly describe the control algorithm:
- we go through the touches
- go through the list of objects
- find the closest to the touch and assign it the ID of the parent
- then we assign x and y to the object of touch by id
maybe someone has a source with a code where such a problem does not occur?
the examples from my last post have the same problem, so I don't even know if it is possible to fix it

I'm just tired of coding, I wanted to draw something

Do you have like a minimal working example of the issue ?
as in some code?

It looks like the limit by the touch screen resolution. Is the shortest line between touches of two fingers diagonal or vertical/horizontal?

i dont know for sure, and i cant imagine how to check it , i think shortest lines for vertical/hor/diag are same
I asked my friends to check it, they also have this problem
did you have this when you ran your example touch-01?

ok , i checked minimal distances by your example :
horizontal : about 110 px
vertical: about 80 px
diagonal: about 70 px

Try the touch-02

On the 10" tablet I've got the shortest line between touches about 27-50 pixels.
