swiping screen 1 to screen 2 - not working (3.5 vs 3.6)

[poweredge]

I dont know if this is a bug of a feature but i upgraded from 3.5 to the 3.6 branch (beta now but tested with master/stable as well) and i now notice i cannot swipe on my touchscreen between the 2 screens. i thought it might be an issue of browser but i tested with 2 versions, and the older ones swipe but the newer one dont.

Any clues?

edit i can film it but lot of personal info on it either .. so difficult to show
