Hello,
Deskscape is designed to stop running in the background whenever you open
a window full screen . When you close the windows Deskscapes restarts itself.
So you might see that stop and restart of the dream.
With an SSD drive the dream will still stop and restart maybe a tad bit faster
and maybe not .
Hope your Installing a SSD drive for other reasons though.
Your present HHD drive may be faulty in some way causing you some issues.
You can try a try a Clean Boot so Deskscapes can run without any other apps
running and see how it works for you in case their is an app. causing you a problem.
