Random Top bar appears with split mode, and for the life of me, i cant get rid of it.

Hi All, seemingly at random (probably me pressing a rouge keyboard shortcut),
this random bar appears and takes over my entire workspace. By default when it appears it seems to stack new windows. But when i switch to normal tiling mode, the bar doesn't go away, and windows loose their gaps.

I'm assuming I'm pressing some shortcut by accident. but honestly I don't know what I don't know here. Any help is appreciated :)

Thanks!

This happens when you set the workspace itself on stacked (this screenshot) or tabbed mode. To avoid it, set individual windows to stacked instead.
