Panel with auto hide and gap between screen edge won't stay visible

If a panel is set to auto hide and to leave a gap between itself and the screen edge, then moving the cursor to the screen edge will cause the panel to appear and immediately disappear unless the cursor is moved up during the panel appearance animation.

I came here to post the same thing. And it's not the same issue, but I think it makes sense to extend the button click area as well as the panel hover area to the screen edge, regardless of the gap size: #233.

This is the same issue as #149. It's likely not a panel issue but an issue with cosmic-comp, where there are 1 pixel lines along the bottom and right screen edges that block input. It works properly if a panel is on the top or left screen edges.

I'm having a similar problem. With Dock settings autohide enabled and gap enabled; I move my mouse to the dock past 'the gap' (i.e. the very bottom of the screen), it pops up then auto-hides immediately.

One thing I found while messing around: Manually changing the value in ~/.config/cosmic/com.system76.Cosmic.Panel.Dock/v1/margin below 4 "hides" the problem.

And to make this more frustrating, sometimes, but not always, when I re-save Margin as 4 (the default), the problem won't comeback until I restart or log out of my current session.
