System Information 1:

Blender Version:
Broken: version: 2.90.0 Alpha, branch: master, commit date: 2020-06-30 08:35, hash: 55ae55af66
Worked: 2.83.1

Short description of error:
This is a regression in Blender 2.90.0. In Blender 2.83.1 when a mesh is the subject of a boolean modifier, it can be modified in edit mode and the modifications can be seen in real time on the object with the boolean modifier. With Blender 2.90.0, the modifications made in edit mode do not show up on the object with the boolean modifier. They only show up after switching from edit mode back to object mode. Here's a video:

Exact steps for others to reproduce the error

Create two objects and make sure they intersect in some way. I will call this objects Cube and Target.
Select the Cube and give it a boolean modifier with the object Target as the reference mesh for the operation.
Select Target and enter edit mode. In 2.83.1 you'll notice that Target still has an impact on the Cube while in edit mode while in 2.90.0 Target does not have an effect on Cube anymore while in edit mode (You may need to be in a wire frame mode to see it).

Here's a .blend file with steps 1 and 2 done.

I am not exactly sure why this modifier does not have option to show results in edit mode. I would guess that it is because with various modes it would be rather difficult to implement that because manipulating existing geometry can lead to it's modification. or in case of union, you would be able to modify geometry of other object?

In any case, thanks for the report, but the issue reported here is a request for modified/improved behavior and not a bug in current behavior. Closing as this bug tracker is only for bugs and errors.

Hello

i dont really know how to change this task status, so sorry if i did wrong

let me describe this bug (yes, its bug, not request) in very precise way - in 2.9 at moment there is no switch "display modifier in edit mode" onto boolean objects as it ever was in blender before - i attached screen (left 2.8 right - 2.9)
and its absolutely not matter, which operation is performed - dif, union, inters,- boolean modifier now hasn t this switch as before did

@impacman looking at Blender 2.79, 2.82a, 2.83.1 and 2.90.0, it seems the boolean modifier doesn't have a "display in edit mode" button when using the factory defaults (see below). The issue you're describing is a request to a change in behavior (the boolean modifier getting a display in edit mode button) or a issue with the add-on you're using.

Hope this helps.

Load factory defaults by selecting from the top of Blender File -> Defaults -> Load Factory Settings

okey, let me describe it in another words again (oh my...)

in 2.9 when you edit cutter of boolean object in edit mode its impossible to see end result onto boolean object

Sorry, I was seeing two different things. I will try modify your original report to better explain the issue.

Sorry, re-reading stuff I'm seeing all sorts of things I've missed. I'm sorry, today's just a weird day. I'll leave the handling of the rest of this task to someone else.

It's worth noting that the 2.83 behavior is restored when there's a generative modifier (e.g. Bevel, Weld, or Array, but not Smooth, Simple Deform, or Displace) on the cutter object. It's probably tied to when the cutter's BMesh conversion is handled.
