Blender Version
Broken: version: 4.0.0 Alpha, branch: main, commit date: 2023-09-08 13:21, hash: 4b217df080a3
Worked: (3.6)

Short description of error

Circle select in edit mode on Blender 4.0 is not snappy as Blender 3.6.
when I click and drag with circle select on vertices or edges or faces it's kinda laggy. on Blender 3.6 I get around 90 fps while selecting with circle select tool but in Blender 4.0 it's around 30fps.

Exact steps for others to reproduce the error
1- create a UV Sphere
2- add subdivision surface level 2 and apply it (this step is just for better visualization not necessary)
3- click on UV Sphere and enter edit mode
4- select 'circle select' tool and click and drag on elements (like vertices)
5- compare performance to Blender 3.6

Hi, thanks for the report. Tried with slight more dense mesh (200k verts), no performance difference here on Windows (4.0 build)

Could you verify the problem with factory preferences?: File > Defaults > Load Factory Settings

Thanks for reply, yes it happen with factory preferences too.
I also notice enabling x-ray will fix problem somehow.
I attach a video with fps on screen.
and also it is not related to number of vertex.
it was ok in Blender 3.6

Thanks. Noticed some difference in fps between 3.6 and 4.0
I'll confirm for now.
