This issue surfaced after a system update a few updates back. Whenever I start Thunderbird now it always starts unmaximised even though on last shutdown it was maximised, and when I reply to a mail or compose a mail that starts unmaximised as well. Until the system update these components of Thunderbird always started maximised as required.     I'm on version 61.0a1 of Thunderbird.     Is anyone else seeing similar issues?

I've checked this under both KDE and Gnome with Xorg and the same thing happens under both. I've also checked the nvidia settings app and it does the same thing, but firefox which is also version 61.0a1 doesn't appear to have the problem (firefox's issue of displaying a black backdrop window and then the main window at launch, and having to manually close both windows at shutdown seems to have been rectified).
