Short description of error
If I try to paint vertex colors to second layer, old Vertex paint mode still put the result into 1st layer

So here is the file

Try to paint one layer, then another with sculpt paint mode.
Then switch to old Vertex paint mode and try to paint into 2nd layer.

Just to note, it seems every single tool that can change colors on the mesh is impacted by this bug (so there is no workaround at the moment). It would be great if fixing this bug can float to the top of Joseph's todo list.

I cannot reproduce this bug anymore in the latest master. This might have already been fixed recently with 575ade22d4 ?

I fixed the color error. I wasn't able to reproduce the picker crash, are you invoking it from the S hotkey or somewhere else in the UI?

And yes open another report on the picker crash, I'd appreciate that.

Done: #97608 (Crash. Vertex painting. Picking vertex color with S crashes Blender.)
