System Information
Operating system: Linux-4.15.0-91-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: GeForce 940MX/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 435.21

Blender Version
Broken: version: 2.81 (sub 16), branch: master, commit date: 2019-12-04 11:32, hash: f1aa4d18d4
Worked: (optional)

Short description of error
[Please fill out a short description of the error here]
I have array of objects. And i want to give scroll effect. Now when i use cube on it to display only overlapping objects it show only one which come fully under it. Like if i scroll and half box from it go out it will remove whole object. In ideal case it must show half of that object.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

Create a cube (representing post on the mobile screen)
resize it
Add array modifer
Create new cube
overLap it on arrays of cube(post)
Select Post array and then add boolean modifer
then intersect ( in boolean modifer )
It only showing post which come fully inside it

Please add a simple blend file to help redo the bug.

The author can get the desired behavior it he put the "Bevel modifier" at bottom after the "Boolean modifier".
Also the "Posts" need apply scale and merge, this will fix the problem too.
I guess it is not a bug.

There are many boolean-related bugs.
Probably the bug here has already been reported in a more specific way.
And from @Rigoletto comment, the way the modifier is being used is not appropriate.

Thanks for the report. Unfortunately the scenario described is too time consuming for us to track down, we require the bug reporter to narrow down the problem.
