## Description
When panel restarts, tray icons, created by qt5 applications, don't appear in notification area.
Only application restart solves problem until next panel restart.
I checked following applications (all are affected):
keepassx, qsynth, qjackctl, cadence, clementine, vlc
However, starting panel from terminal, I don't get any errors,
like in https://bugzilla.xfce.org/show_bug.cgi?id=11522

Wine applications especially. Frequently, when the dialog window is closed again, the application's button in the window button list starts blinking. This is despite the fact that the application already is active and has focus.
This smells like a bug. I don't think the currently active/focused window's button should be able to blink. It's unnecessarily distracting, and there's no intuitive way to stop it when it happens.
To make it stop, one has to focus a different window and then the application again.

The keyboard cursor is first still blinking but disappears after a first mouse click. From hereafter there is no visible response to mouse or keyboard actions beside mouse pointer movement. Alt+F4 or Alt-tab or the keys to switch desktops all do nothing.
This launcher bug has been there a while - a few years. I never found anything reported or a solution, so it could be a local config issue.
A crash-landing solution is Ctrl+Alt+F2, and after login:
```
pidof xfce4-session | xargs -r kill -9 && startxfce4
````
BTW, I always run `startxfce4` from the terminal console user login.
When I haven't killed my session yet, I see an App launcher in my `ps aux`, which I suspect, but even a kill -9 just renders it defunct (ps aux), without returning my desktop on Ctrl+Alt+F1. Maybe the underlying cause is that gvim always spawns? The App launcher might get zombified as a process?
There might be a better session saving --reset, but it is not any of these:
```bash
xfwm4 --replace --display=:0.0
xfce4-app-finder --quit --display=:0.0
xfce4-app-finder --replace --display=:0.0
xfce4-panel --restart --display=:0.0
xfce4-panel --quit --display=:0.0
```
Running any of these (except one of the --quit commands) just seem to hang.
There doesn't seem any suspicious logs in my `journalctl -xb` regarding this, (syslog messages since boot).

I experience strange issue with Xfce4-4.18.0.
xfce4-panel starts and works fine until I try starting Telegram client.
After that panel immediately crashes on segfault.
I tried rebuilding xfce4-panel with debug info (I am under Gentoo).
However, the issue happens only inside 3d-party libs. See below.

I'm a happy user of XFCE, thanks for making XFCE and sharing it as Open Source! :pray:
When I log into X about every second time, xfce4-panel shows a pile of overlapping pop-ups saying "Plugin [..] unexpectedly left the panel" — screenshot below — that force me to either
- click "Execute" multiple times or
- do "pkill -9 xfce4-panel && xfce4-panel &" on a terminal.
If that could be solved, that would be fantastic.
For potential causes I can think of:
- use of some de-facto dependency before its available,
- use of a non-monotonic clock and NTP/clock updates hitting at the same time, and/or
- some other race condition.
Thanks and best
Sebastian

To the left of it I have the sensors plugin with two data sources.
Right mouse clicking these redundant icons does nothing, i.e. this is something which doesn't belong to either of these two plugins. I've no idea what's going on.

It does not seem to matter if it comes from a built-in feature (displaying seconds on the clock) or a plugin (system monitor). Removing the system monitor plugin from the panel and disabling the seconds on the clock stopped the stuttering. Suspending the processes of the plugins with 'kill -19' also worked, but only on the plugins as the clock doesn't have its own process and I don't want to suspend the whole panel.
This is how it looks like: I let the unigine-superposition benchmark run in game mode (standing still for most constant frame times) and traced the frame times with mangohud. Displaying seconds on the clock has already been disabled but the frametime spikes produced by the clock looked just the same as these:

long-time observation here. Some apps such as the [Nextcloud desktop client](https://github.com/nextcloud/desktop) will always show the black/white symbolic icon in panel's Status Tray.
`Request symbolic icons` is disabled in the plugin settings. Likewise, `Use monochrome icons` is disabled in Nextcloud.
On other DEs I have seen colored icons, or at least a green checkmark on the white cloud icon. This doesn't seem to show in Xfce panel.
