Cinnamon: Panel is stuck

[dkuteynikov]

 * Cinnamon 4.4.8
 * Linux Mint 19.3 (Tricia)
 * AMD Radeon™ RX Vega 10 Graphics; VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Picasso (rev c1), Subsystem: Hewlett-Packard Company Device 8615, Kernel driver in use: amdgpu, Kernel modules: amdgpu
 * Kernel 5.3.0-46-generic x86_64

Issue

Cinnamon panel gets stuck and is not being hidden again. Even if I go to the panel settings and turn OFF & ON again the "Auto-hide panel" mode, it doesn't help: the panel remains visible, only the windows' size change. After Cinnamon restart it restores normal behaviour.

Steps to reproduce

Turn ON "Intelligently hide panel".
Sometimes it happens when I work in the Android Studio.

Expected behaviour

Panel should be hidden if I have any maximized windows and my cursor is outside the panel's area.

[icarter09]

@dkuteynikov are there any other steps involved to try to trigger the issue beyond just turning on "Intelligently hide panel"?

[dkuteynikov]

Unfortunately, I don't have exact steps, it happens randomly, but maybe the system overload may affect this, because it usually happens when my PC is running out of memory & CPU resources. But I cannot guarantee this.

[icarter09]

@dkuteynikov no worries. I'm going to keep "Intelligently hide panel" enabled and see if I run into the issue as well.

[dkuteynikov]

Thank you! By the way, another idea came into my mind: that issue could be related we the full-screen mode, because I often use it in Firefox, Viber, Telegram, Android Studio, ...

[dkuteynikov]

I think I have found the exact scenario: I noticed that it most often happens when I close an app by middle-clicking on it's icon in the task bar.

Try this scenario:

1. Open Text Editor, it's window should be maximized
2. Open Firefox, it's window should be maximized
3. Close Text Editor by middle-clicking on it's task bar icon
4. Bingo! The panel is stuck now.

P.S.

• In Grouped Window List applet I have set "Left click action" to "Toggle activation of last focused window", and "Middle click action" to "Close last focused window in group"
• In Touchpad settings I have enabled "Tap to click" and set "Click actions" to "Use multiple fingers for right and middle click" (so my laptop emulates a middle click with three-fingers tap)

[Pentarctagon]

I have also encountered this issue. The way I found to reproduce it:

• Don't have xed pinned to the panel.
• Open xed.
• Close xed by middle clicking the icon on the panel.
• Panel no longer auto-hides anymore.

I'm using a fully updated Mint 20.

[rogeriodomingos]

I can also reproduce this issue using the steps @Pentarctagon has stated.
It happens with many application like Xed, Calculator, Rythmbox, etc.
Two exceptions that I've noticed are Terminal and Files.
This isn't the only scenario where this issue has happened with me however, sometimes it appears to happen randomly.
I am on Mint 19.3.

[rbb8403]

I am also having this issue. I thought it was random until I noticed that it happened when I middle-clicked to close Discord. In general, middle clicking an icon in the panel to close the associated window keeps the panel visible in auto-hide mode, obstructing the screen. A few things to note:

1. This bug happens when the panel is set to auto-hide mode as well, not just intelligently hide.
2. It doesn't occur when I middle click to close a pinned program.
3. Despite being visible, the panel still behaves as if it was hidden - it takes a second to respond, as if it has to pop up from its hidden state.
4. The panel covers content, rather than shrinking the available workspace.
5. The issue persists until I restart Cinnamon - either by logging out and logging back in, or restarting it with the troubleshooting option.

I am using Mint 20 with Cinnamon 4.6.6. I experienced this bug while using Mint 19.3, before I upgraded. However, my laptop is still using Mint 18.2 with Cinnamon 3.4.6, and it doesn't have this bug.
