I have an old build from 2019-06-24 and vertex colors are working in Sculpt Mode. If I save file in old build and open it in latest 2019-07-22 and switch to Sculpt mode it turns black so it looks like something was changed between 24.06 and 22.07

blender/blender@1715c396e4 introduced the issue.
Seems like the shader parameters were renamed, but change was not done for sculptdrawing.

Tested latest 1178046ed222 from 2019-07-29 and vertex colors and textures are still not working in Workbench Sculpt Mode on Windows. As far as I can see there is a fix for the problem but the problem is still there, am I missing something?
