Top rows hidden in fullscreen mode

I’ve started using OmniOutliner over the last couple of weeks and I’m having a strange issue when I’m running it in fullscreen mode. Whenever I close the sidebar, the top few lines goes outside the window and I cannot get the back in. I can see them when I scroll, but letting go of the trackpad makes them bounce back out of view.

The only workaround is exiting fullscreen and entering it again, which gets quite tiring if you’re trying to work with the document under time pressure.

Is this a known issue?

This is on our list of bugs to fix, though I don’t have a target date. Fortunately, you’ve already discovered the workaround; apologies that you need one!
