This bug is still present with the current release candidate Octave 6.3.90 on Ubuntu 20.04 LTS.

I see the same wrong behavior of the Octave GUI after closing the maximized window. I also have the whole window "decoration" missing after the second Octave GUI start (like the screenshot in comment #10).

I use (self compiled from release tar-ball) Octave 6.3.0 on Ubuntu 20.04.3 and an X11 seesion (i.e. no wayland display server) with Gnome. It is a quite freshly installed "vanilla" Ubuntu linux.

In my setup, there are also two monitors involved, the problem happens on either of them. (The problem disappears once I remove the second monitor.) Maybe it is relevant that my two monitors have different size (meaning different numbers of pixel height) and are arranged side by side in the display settings. (This is probably a typical home office setup, a laptop plus a monitor next to it.)

I could supply more information if it is relevant.

Now a better screenshot only of the screen with problems. The problem is not only the wrong size but the impossibility of resize it.

Good point! I am also seeing some minor issues on Wayland with Qt applications. Octave's main window is slightly too high after a restart in full screen mode such that the status bar is not visible. However, everything work as expected and I can quit full screen mode.

TeXStudio, e.g., shows a too wide window when leaving full screen mode.

Making another test it seems that the problem only happens with two monitors. When I remove one monitor and use only one the problem not happens anymore. However if i plug the second monitor and maximize I got the weird full screen without task bar and other commands.

I have annexed two screenshots of my two monitor setup. .

Could it be an Xorg-vs-Wayland issue?

Full screen mode works as expected on Debian 11 with Gnome.

Is it possible to provide screenshots of the main window states in full screen mode?

It seems that bug #61183 is the same as the one reported here.

Is bug #61183 a duplicate of this one?

The same problem happens in Ubuntu 20.04 with Octave 6.3. Restoring default windows layout makes the window normal but doesn't solve the problem.

No. Unmaximize, move and resize appears in gray and the shortcuts do not work as well. Is impossible to do these commands after the maximization.

Thanks for your attention.

Thanks for the report. Are you able to open the windows menu via Alt+Space and unmaximize the window via this menu?

I am using Linux Mint 20.2. I have build Octave 6.3 and got an unexpected behavior.

When I run the GUI for the first time everything is ok, however if I maximize the GUI and close the program. When it starts again it comes in a full screen configuration without the mint taskbar and without the buttons to unmaximize, minimize or close the program. The only way to close is with alt+f4 command. If I use the windows key the task bar appears again but the unmaximize option stay in gray.

So after maximize it is impossible to unmaximize because of the lack of the buttons on the top right. All title bar disappears. Also is impossible to grab the window and move it to other monitor.

After trying reinstall sometimes, I see that the problem is related with the file /home/luiz/.config/octave/octave-gui.ini. If  I delete it the program think that is the first time that I am running the GUI and the behaviour is normal again. Except that I can't maximize the program because is impossible to unmaximize it and problem starts again.

It seems that when I close the program maximized, it rewrite the .ini file on a wrong manner.

I have annexed two config files: file 1 is before the maximization and file 2 is after the maximization.
