Running in VirtualBox with Ubuntu MATE 20.04 20200119 daily. I can confirm that this behavior exists.
However, following the steps listed to reproduce this I was unable to get this to occur. Performing the steps multiple times. On the 3rd attempt this behavior manifested itself. After this occurred the behavior repeated itself consistently. ** Attachment added: "VirtualBox_Ubuntu-20.04_19_01_2020_17_11_11.png" https://bugs.launchpad.net/ubuntu-mate/+bug/1854383/+attachment/5321600/+files/VirtualBox_Ubuntu-20.04_19_01_2020_17_11_11.png -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/1854383 Title: Extra window decorations are created on windows with client-side decorations. Status in Ubuntu MATE: Confirmed Status in gtk+3.0 package in Ubuntu: New Bug description: Steps to reproduce after a minimal/full install of Ubuntu MATE: 1. Start up a Gtk3 application with a header bar (tested with Gnome Software) or a browser (such as Firefox) without using a standard window title bar that saves the position and size of the window before it was closed. 2. Maximize the application window, then close it without changing the window size 3. Relaunch the application and resize/unmaximize it After this, dummy window decorations will be created around the window. This issue has been tested on a Dell XPS 9570 and using Gnome Boxes 3.34.
