Short description of error
Rather than the correct red wax MatCap, the Sculpting workspace is now coming up in Studio lighting mode after today's changes.
Exact steps for others to reproduce the error
Start with no config or --factory-startup, switch to Sculpting workspace. Note lighting mode.
Should be starting up in MatCap mode as before I believe. If you use the + tab to create a new Sculpting workspace, the newly created workspace is correct.
