Tray icon disapears after waking up the device from sleep in linux

[jacktheripper19]

Hello, thank you for your hard work on this amazing matrix client. just wanted to point out a small bug that happens after waking up the device from sleep state on linux, the tray icon become invisible. This happened to me on both KDE plasma and Gnome 40. Also the same issue on deb package for ubuntu and AUR on arch.
The place for the tray icon is still there but it's invisible. This can be fixed by either restarting the app or changing the state of the icon by receiving a message or going offline for example.

Does the same happen with Element?
And does the same happen with other (electron) applications by any chance?
Xorg or Wayland?

For me with Gnome and Xorg on Arch, tray icons are often messed up or missing after screen off, standby or similar. Alt+F2 and then "r" to restart brings them back, so I'm not sure if it's the applications' fault at all.

I think we talked about this before:

• Also happens for me on awesomewm (xorg)
• Also happens with Element
• Also happens with telegram (don't know if this uses electron though)
• Interestingly, does not seem to happen if I cd to the element-desktop directory in our build setup, and run electron . in there to launch the app

I just installed Element and can confirm that it has the same issue. I don't have any other electron application with tray icon. Wayland is not configured in my machine so can't test with it. It happened to me on KDE as well so I think it's more of an Electron issue in this case. I have no problem with it since I can do a workaround but it should be fixed from a user experience perspective.
Also, restarting KDE Plasma with kquitapp5 plasmashell && kstart5 plasmashell doesn't seem to fix the issue for me.

What have window decorations to do with the tray icon? 🤔
