Panel set to autohide may not always retract

[S Webb]

System: Noted on all of: Ubuntu MATE 14.04, 14.10, 15.04

I set up a panel on the left side to launch applications . The panel is set to autohide. The bug is that if you launch a program from the panel, and immediately move the mouse away from the panel, the panel will stick open. This is very easy to reproduce. Further, the panel will not retract until you again move the mouse over the panel and then away again.

This only happens when launching one of the applications from this panel. It does not happen if you just hover over the panel, then move away.

Image: Shows stuck panel after program launch. Note mouse cursor is away from panel after a program launch. It should be hidden in this situation.

Not sure if it affects more distros than Ubuntu MATE but you could report it on https://github.com/mate-desktop/mate-panel/issues

This is now fixed upstream.

"It surely comes back as we've reverted the fix which caused a regression"
The patch was reverted , so no fix at this moment.

Observed in focal and hirsute as well.

I just did a fresh install of Ubuntu MATE 20.04LTS on a Dell Optiplex 390. I am still having this problem... at least 5 years after reporting it as a bug. Why is this still a bug 6 versions later? Why is it marked as "low priority"? When the task bar doesn't hide like it should, it covers up applications and prevents access to things like scroll bars and buttons... I'd have to say that's a pretty high priority since it interferes with the overall function and productivity of the OS & DE. When can we expect a real permanent fix for this ongoing lack of proper functionality?

I would recommend to report this bug upstream at https://github.com/mate-desktop/mate-panel/issues/ to get faster response. Then share a link here.
