When the wallpaper changes due to its interval (31 mins in my case) my system gets frozen for like 4-5 seconds, even the Windows cursor. Then I see the wallpaper changing and I recover control of the cursor again.

The weird thing is that when I manually force a wallpaper change this does NOT occur at all, the system doesn't froze. There isn't even a minor hitch in the cursor.

Here is the file. It happened at 23:49.

With a function hotkey:

Is this going to take much more to be solved? it's starting to get really annoying...

Also, this doesn't work. Even when disabled it keeps doing the transitions anyway.

It seems it needed a restart for it to work. But the several seconds stall each time the wallpaper is changed keeps happening.
