It's an excuse.
You can see on your eyes that ordinary fences (not linking to folders) are displayed correctly
So technically, it's fixable.

I would believe you if it was occurs on all the fences.
I must say I was very surprised by this response. I expected to get a logical response.

I have a Lenovo laptop and i have energy management software. In my case, every time I set a "super energy saver" then this problem occurs.

So this is a serious problem for those who have a laptop ..

i don't recommend you to ignore so many people who have a laptop and from time to time want to save energy.

I loved the fences one .. But if this bug will not fixed (and this is bug) so I do not buy it.

Just to be clear...it's Fences' Folder Portals that needs Aero, not 'normal' fences - hence your screenshot...

Ok so who am I to argue with the developers of the software ..

So every time I do a "super power saver" so I have to suffer this terrible black?

I have an ideas. If it can not be resolved, then at least you can make it less bad.
I have 3 ideas:
1) change the terrible black to another More beautiful color. I am sure that no one likes the black color.
2) instead of black color, set an Background image.
3)the fences folders will Disappear when you disable the desktop composition. But this idea is the worst

Hope you got one of my ideas.
I think the idea number 2 is the best.
You can make a picture that is a logo of fences.

I hope you received the one idea and you can do them.

I do not know who to talk to and I do not mean to do it..
Better you do it.

If not then it leads to idea 3.
