I tried reproducing it with 5.60.0, but it seems that it is fixed now. Does it still happen for you on the latest production release?

It seems to be fixed on 5.60.0.

It looks like they totally changed the way minimize works (for the better, I think). Now X goes to the tray, while minimize just minimizes, which is how other programs work.

It seems like this issue is still happening via slightly different inputs.

Steps to Reproduce

• Make sure "minimize to system tray" is set in preferences;
• Open and maximize the Signal window;
• Minimize the Signal window (it minimizes to the taskbar);
• Click on the system tray icon (This causes the minimized program to hide into to the system tray, disappearing from the taskbar);
• Click the system tray icon again to open the Signal window back up

At this point, the window will be unmaximized, having forgotten it was maximized previously.

This is on windows desktop 6.22.0 production, on Windows 10.

It looks like 6.23.0 changed the behavior a little, but the bug is still there.

Now,

• Make sure "minimize to system tray" is set in preferences;
• Open and maximize the Signal window;
• Minimize the Signal window (it minimizes to the taskbar);
• Click on the system tray icon (This causes the minimized program to open back up)

At this point, the window will be unmaximized, having forgotten it was maximized previously.
