I've also installed xposed framework with a few modules and i use the "Full!screen" app, but they haven't given me any problems so far.
Not all applications compatible with multiwindow, especially if you don't update your apps regularly.
And you can't use the built in "disable multiwindow" inside the original multiwindow menu (the Arrow icon on the bottom middle).
If you use this, you'll get the System UI error message.
I learnt it the hard way & I have to reflash my ROM
