Titlebar doesn't hide on apps with native Wayland rendering

[icher]

Extension working as expected on apps using Xwayland. Some apps using native Wayland rendering, and extension doesn't work: window is maximized and titlebar still showing. Gtk and Qt apps affected.

Test apps for Fedora (other distros might have different combinations)

Wayland GTK: transmission -- doesn't work. Xwayland GTK: gimp, audacity -- working as expected.

Wayland Qt: qbittorrent, KeePassXC -- doesn't work. Xwayland Qt: Virtualbox, VLC, Kdenlive -- working as expected.

You can check if app using native Wayland or XWayland with xeyes (xorg-x11-apps): the eyes will move if the cursor is over an X or XWayland window.

Fedora 33 Gnome 3.38.5 Wayland

I have just tested NeoVim-Qt to reproduce your issue and it is hiding the title bar. Could you explain what you mean by "doesn't work"?

By the way, the newer version is intended for GNOME 40 even though it will work on older releases (such as 3.38).

It's simple: neovim-qt is maximized and titlebar is still here (same for qBittorrent and KeePassXC).

Well, it's strange. Wayland session? Can you please test qBittorrent also?

Yeah, it doesn't work on previous versions either. I just finally decided to make a bug report.

Yeah, I am on Wayland. Just tested qbittorrent as well and it works on that too. Do you have any other extension that would conflict with this one?

Ok, it doesn't work for apps with native Wayland rendering, only if app running under Xwayland.

[velitasali]

Hm. Are you running these on native wayland?

[icher]

Hm. Are you running these on native wayland?

Yes. Some of these apps using Xwayland and extension working as expected. Some of apps using native Wayland rendering, and extension doesn't work. I thought it works for both, sorry.

[velitasali]

It should be working. Let me see what is going wrong there.

The libreoffice applications also don't hide the tittle bar.

It does't work with QTikz but it works fine with terminator and the like on my machine. Hope that it helps narrow it down

I just upgraded to Gnome 40 and switched to a wayland session. The gnome-terminal title bar is no longer hidden for me when maximized.

More applications to add to the list, the terminal emulator kitty as well as foot doesn't hide the title bar

Additionally, Firefox when run with MOZ_ENABLE_WAYLAND=1

[velitasali]

xprop (the program this extension uses to alter window properties) doesn't support Wayland windows. I am not sure if there is any other way to alter those values for Wayland.

Are you using a tiling manager? I think this works only with gnome tiling.

Wayland programs (wayland "clients") render their own titlebars instead of getting them from the window manager, so it's not possible to hide them right? Probably should write off Wayland support in general.
