I tried it also as screensaver, when i activate the screensaver with a not working dream it comes up, then freeze.
One problem at a time.
Only some DeskScapes Standard Builds Work normal, other Standard Builds (Spring, Vintage) give "There are no parts to disable in this background". They give a complete Black background when Apply.
So your issue is with Hybrid dreams only, yes?

Spring, Vintage and planktonci give --> "There are no parts to disable in this background" --> Complete Black Screen by Apply.
Planktonic is a video dream, not dynamic - and would not have any 'parts' to disable. Were you mistaken in including it here?
The only thing what changed is what i say in my other post. Now the default transparency is 100% visible, now i can see my Fences.
I hope this value would stay at 255 - 100% visible, when i change something / or not and push the OK button.
If so then we can close that post.
What change - from what post - post an image of what you changed, where, and if you change it back to what it was, does it work?
