How to restore windows registers from saved desktop

Question

I save a few different windows registers using M-x r w and then save the entire desktop with M-x desktop-save.

I then restart Emacs and load the desktop using M-x desktop-read. If I do M-x r j do jump to one of the previously saved windows registers in the saved desktop I get an error message saying Register doesn't contain a buffer position or configuration.

If I do M-x list-registers every registry is described as Register X contains a rectangle starting with an Unprintable entity.

I do not run Emacs in a terminal, it's a full GUI Emacs and desktop-restore-frames is set to 't'. How should I do to save frame configurations between desktop sessions?

Answer 1

Rather than use window registers, use frame registers. Namely, save the configuration of the frames with frameset-to-register. It appears that Desktop correctly handles frame registers, but not window registers, and they perform largely the same function.
