Fullscreen window low FPS.

Hi,

I am using Lightpack for ambient lighting when watching movies.
In order for the lightpack too detect the movies playing I have to use “fullscreen window”.

When Using Kodi 16 and “fullscreen window” the UI is smooth and quick and FPS is 60.
When Using Kodi 17 and “fullscreen window” the UI is laggy and the FPS feels likes 25 (for some reason the FPS
display was removed from the system information….), When getting back to real full screen the FPS increases and
The UI is fast again.

I am using WIN10 and i5 6400 built-in GPU.

Can someone check this and confirm?
