autohide panel shakes a little when opening

On my end, it happens when continuing to move the cursor against the screen edge while the panel is revealing itself (just quickly moving the cursor there and not moving it doesn't produce a shake).

I think this is possibly not a panel issue. My assumption is that the pointer leaves the panel when continuously moved against the edge. I'll test to see if creating a slightly larger input region than the size of the panel fixes it though.

Thanks so much for looking into it! I agree with your assumption, that's what it seems like its doing

While I'm not sure, this commit might be related pop-os/cosmic-comp@929f4fc, since the panels don't shake on the left or top edges. Other issues also report mouse input not being registered along the bottom and right edges.

This was a problem before that commit btw

Just following up on this, I don't think I can fix the issue with the input region.

It seems likely that this is a comp issue.
Unrelated issue, but can also cause a shake:
When e.g. an extended non-autohiding floating panel is anchored to top, and a floating autohiding dock is also anchored to top, the dock reveals only when the cursor is near the side of the panel away from the screen edge. Continuing to move the cursor towards the screen edge makes the dock hide again.
While an unlikely setup, the dock should probably stay revealed when the cursor is at the screen edge).
