System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 527.56

Blender Version
Broken: version: 3.5.0, branch: blender-v3.5-release, commit date: 2023-03-29 02:56, hash: 1be25cfff18b
Worked: (newest version of Blender that worked as expected)

Short description of error
In grease pencil in vertex paint mode, trying to select strokes with the same vertex color through "select > color attribute" does not work for strokes made with a brush that use a texture. That is despite these strokes being successfully colored by assigning them a vertex color.

Exact steps for others to reproduce the error

Open the supplied blend file.
Go into vertex paint mode for the GP object
Set selection mask to stroke so you can select strokes
Select one of the green strokes on the left (use lasso select)
Go into the "Select" menu and choose "Color Attribute"
In the redo panel change the Threshold from 0 to 1
All green strokes will now be selected (this is the desired result)

Repeat these exact steps for a red stroke on the right. You will see that no additional red strokes will be selected.

Additional notes
I want to emphasize that the vertex colors have been correctly assigned. I don't know why I need to bump the threshold up to 1 for "select by color attribute" to work, that seems to be a bug in itself but is not the focus of this report.

You can verify that the red strokes have a vertex color assigned to them by going into the "Paint" menu and choosing "Reset vertex color". The stroke will turn black which is the color without any vertex color assigned. So the vertex color is there, assigned and coloring the stroke.
