Blender wrongly thinks I clicks a scale-cage manipulator that closest to camera - which is not the closest to mouse I want to click the green manipulator, not the red one.

However, if two manipulator (red &amp; green) appear moderately close together from the camera, Blender will think that I click the one that is near camera (red).
The below dot-gif image shows my clicks.
All of 3 scaling tests were done by clicking the green.

In the first two tests, Blender wrongly think I click the red manipulator.

In the last test, before I clicked, I rotated camera a bit and get the expected correct result.



How to reduce the distance threshold that Blender use?


^ To make testing convenient, I wish for an answer that works when I click the yellow zone.
Currently, if I click the yellow zone, Blender will wrongly think I click the red manipulator.
However, if I click the cyan zone, Blender will correctly think I click the green manipulator.
Environment :

Blender 2.81 &amp; 2.83 &amp; 2.90 &amp; 2.91(experimental) in Windows 10.
Blender : switching because Industrial and Blender-default keymap doesn't help.
Windows : It can't be fixed by Display&gt;Scale and layout&gt;Advanced scaling settings&gt; = 100%.

Environment that there is no issue:

Blender 2.81 in Windows 7.
Blender 2.81 in the problematic computer.  It needs factory reset.
The trick has no effect on Blender 2.90.

Bounty Reason (old)

HikariTW's answer is a good attempt, but sadly, for my case, it isn't useful at all.

Jachym Michal's is very insightful, but it
doesn't provide any solution except (bug) reporting.

Increality's provides a doable solution.  However, for me, it is (very) inconvenient.

Yudaka's argues that there is no such issue in his machine, and I confirm later that there is actually no issue in one of my computers.
This is due to Perspective view.
I seems that closer control points have larger &quot;active area&quot; around them. because reasons...?
In Orthographic view, the active area around all points is the same :).

Active areas highlighted. When cursor is in 'active area' it changes from a cross ✛ into arrows ✥

This doesn't make much sense from the UI standpoint, the 'active area' shouldn't change due to perspective. 
 It would also be nice if the 'active' point was highlighted when the cursor gets close enough. 

Possible solution:
Suggest improvements on devtalk.blender.org or rightclickselect.com and wait until they're implemented.
