Full-Screen windows behind XFCE-Panel

[matt-hires]

When switching the displays between my Multi-Mon setup (Monitor + Laptop) and my Laptop-Display, full screen windows extends behind xfce-panel.
Therefore the xfce-panel is in front of all windows and hides controls on the bottom, which is kind of annoying.

So far the only workaround is to resize windows, to make them full-screen again without extending behind the panel.

If I remember correctly, this is a regression and was working before one of the last updates.

Steps to Reproduce:

1. Check settings (see screenshots)
2. Set Displays to Multi-Mon: External Display (Primary) + Laptop
3. Maximize a Window to Full-Screen on Primary
4. Change Display Profile to Latop-Display, which disables the external display and moves the maximized window
5. Now the window is maximized behind the panel

I can only reproduce if i disable the Reserve space on screen edges for the panel. Maybe you can disable it and re-enable and see if the issue persists.

Hi @bogdancovaciu

Sorry, I forgot to describe reproduction steps.
It’s now edited in the original post.

Re-Enabling Reserve space on screen edges for the panel did not change the behavior.

Please let me know if you can reproduce it.

All working as is supposed on my end. Except the fact that i had to replace the libxfce4ui-nocsd with libxfce4ui as can also be seen on announcements wiki, there was no hiccup.

I noticed that Panel Preferences now also has the Span Monitors option (in dual screen scenario)

and still, all applications do not fall under the Panel.

Changed the Row size, Spanned it, changed the length manually, switched back to Automatically … increase the length and hide options, and none gave me the undesired result, except what i mentioned earlier.

Ok, found the problem - it was a theming issue, which occurs when using “Orchis”-GTK/Xfce4Wm theme.

Changed back the theme to default “Matcha-Sea” and the panel behaves as expected.

And as always, thanks @bogdancovaciu for trying to reproduce the issue.
