Cinnamon: Window preview stays after window closed

[buzo-ffm]

```

• Cinnamon 4.4.4
• Distribution - Arch
• Graphics hardware and driver used: Intel Corporation HD Graphics 620 (rev 02), intel
• 64 bit
• Attach /home//.xsession-errors, or /var/log/syslog (not relevant)
  ```
  Issue
  Sometimes the panel shows a tooltip which does not vanish until Cinnamon is restarted.

Steps to reproduce
There are many ways to reproduce. Maybe the easiest one is:

• Open Nemo
• Hover over the Nemo entry in the panel until the tooltip (window preview) is visible.
• Press Ctrl+W to close Nemo.

Expected behaviour
The panel entry and the tooltip vanishes.

Actual behaviour
Only the panel entry is gone. The tooltip stays until I restart Cinnamon.

I'm not able to reproduce the issue, it seems to work correctly in Cinnamon 4.4.5 (Linux Mint 19.3)

[buzo-ffm]

Did you try to close the window via keyboard shortcut, too, while the window preview was visible?

Anyway, I'll wait till 4.4.5 lands in Arch then.

I'm able to replicate what I think to be the same issue on 4.4.5, Mint 19.3:

Distro: Linux Mint 19.3 Tricia base: Ubuntu 18.04 bionic
Desktop: Cinnamon 4.4.5
Graphics:
Device-1: Intel 3rd Gen Core processor Graphics vendor: Lenovo 
  driver: i915 v: kernel bus ID: 00:02.0 chip ID: 8086:0166 
  Display: x11 server: X.Org 1.19.6 driver: modesetting unloaded: fbdev,vesa 
  resolution: 1600x900~60Hz

Steps to replicate

1. Open any application and hover mouse over panel icon:
   

2. Close application with F4 while hovering

3. Note tooltip will not disappear until logout:

I am experiencing the same problem with 4.4.4-1 on arch, too
It looks like #9040 is related

Updated the title because this isn't actually the tooltip. It's the window preview being left behind.

[Hordeking]

I was able to confirm it as well. It's happening for me. It happens when using ctrl-w keyboard shortcuts (nemo), and when the program closes on its own while the mouse is showing the preview (terminal command exit, and dosemu closing/crashing).

Additional: $ cinnamon --replace also can reset this, so you don't have to log out.

Can anyone reliably reproduce this? I managed to do so twice, but not again.

If you can reliably reproduce, can you share your grouped window list applet's configuration? (Upper right corner button of configuration page, "Export to a file".

Thanks

[Hordeking]

I would export it if I could figure out what you're talking about. Confuguration page of what? How do I get there? I can consistently reproduce it, so that's taken care of.

I can reproduce the same behavior in my window-list applet. I don't use grouped windows.
As a workaround, if you you disable "show title above thumbnail", it becomes just a small black block, which is easier on the eyes.

ps: I have this on a normal linux mint 19.3 updated from 19.2

@Hordeking right-click any item on the window list applet, expand 'Preferences", then click 'Configure..'

In the window that appears, in the upper right corner there's a button with 3 horizontal lines. Click that, select 'Export to a file'

@Hordeking right-click any item on the window list applet, expand 'Preferences", then click 'Configure..'

In the window that appears, in the upper right corner there's a button with 3 horizontal lines. Click that, select 'Export to a file'

The resulting file is in my previous message under the "settings.zip" link.

[Hordeking]

I'm not using grouped windows, either.
Here's my exported config

I can reproduce this reliably. I'm on Linux Mint 19.3. From the system reports:
System: Kernel: 5.3.0-26-generic x86_64 bits: 64 compiler: gcc v: 7.4.0 Desktop: Cinnamon 4.4.6 wm: muffin dm: LightDM Distro: Linux Mint 19.3 Tricia base: Ubuntu 18.04 bionic

For me to reproduce this, I just made a simple bash script.

#!/bin/bash
sleep 5

Double click the file and select 'Run in terminal'. The terminal window will open, hover over the window so that the window preview is shown. Then after the script ends, the terminal window will automatically close. The preview (just the window title text, no window is shown as a preview after it closes) will remain. Similar to the images provided by @tommypyatt

This only seems to happen with the 'Window List' applet. I cannot reproduce with the 'Grouped Window List'.

[Hordeking]

Why was this closed? Was the problem fixed? This seems to be a legit issue, and I don't even have to _try_ to reproduce it to wind up with half a dozen window preview names that can't be dismissed without restarting cinnamon...they just happen as I leave the mouse laying around while running the keyboard.

This isn't a nemo problem. I get it with terminal, ghidra, dosbox, firefox, thunderbird, and pretty much every other program I've tried it with.

Why was this closed? Was the problem fixed?

Yes - click on the hyperlink in the closed message to see the fixing commit. It won't be rolling out to users yet (jut missed yesterdays maintenance release)

[Hordeking]

Oh, cool. I didn't see the hyperlink. Good show!

[parnikkapore]

Nearly posted a duplicate bug report for this - it's very annoying for me. Hopefully there's a patch release soon!

[ugly95]

The update I got this morning has resolved the issue.

Thanks.
