I've been trying to set up screen splitting on my ultra wide monitor to allow for multiple terminals and a standard 16:9 aspect ratio. However it doesn't seem to be creating the splits. Every time I press the key bind that I've set up to switch profiles, I get a notification saying that it has changed however there is no change in look or window operability. It is as if nothing is happening at all. Any insights into what could be causing this would be much appreciated.
