[bug] Title bar buttons are not working on Linux when resizable is set to false and skip_taskbar is set to true

WilfredC64 commented 2 weeks ago

Describe the bug

On Linux when setting resizable to false and skip_taskbar to true on the Webview, the maximize button disappears in the title bar and the minimize and close buttons are unusable with some extra whitespace between the buttons .

Also, when resizable and skip_taskbar are set to true, in order to use the title bar buttons, you need to double click on the title bar which maximizes the window, regardless if maximizable is set to false, and then the buttons are usable.

On Windows and macOS, the above issues don't exists, the issues mentioned above only exists on Linux.

I create the Webview programmatically like:

WebviewWindowBuilder::new(app, "about", WebviewUrl::App("/pages/about/index.html".into()))
    .title("TITLE")
    .inner_size(600.0, 512.0)
    .min_inner_size(600.0, 512.0)
    .center()
    .maximizable(false)
    .resizable(false)
    .fullscreen(false)
    .skip_taskbar(true)
    .build()?;

Reproduction

In order to reproduce the issue, you need to create a webview where resizable is set to false and skip_taskbar is set to true. Doing it programmatically you can reproduce it like:

WebviewWindowBuilder::new(app, "about", WebviewUrl::App("/pages/about/index.html".into())) .title("TITLE") .inner_size(600.0, 512.0) .min_inner_size(600.0, 512.0) .center() .maximizable(false) .resizable(false) .fullscreen(false) .skip_taskbar(true) .build()?;

Existing repo where it's done the same can be found in main.rs in: https://github.com/WilfredC64/sid-device

Expected behavior

When I create a Webview Window which is not resizable and where I skip task bar, I expect that the minimize and close buttons in the title bar are clickable and working.

are you using gnome on Wayland?

WilfredC64 commented 1 week ago

Yes, echo $XDG_SESSION_TYPE outputs wayland and echo $DESKTOP_SESSION outputs ubuntu.

Also I forgot to mention that a previous build of my application using Tauri V1, didn't have the issue. It runs fine on the same Ubuntu environment.

On Linux when setting resizable to false and skip_taskbar to true on the Webview, the maximize button disappears in the title bar and the minimize and close buttons are unusable with some extra whitespace between the buttons .

I can't see the extra whitespace and the close button works just fine.
However the minimize doesn't work but this is something the Window manager decides, it seems like Gnome ignores the request to minimize a window that is skipped from taskbar. This only happens if you launch the app in XWayland (which happens if you run it from within VSCode, if you run from another terminal, it should minimize just fine)

Also, when resizable and skip_taskbar are set to true, in order to use the title bar buttons, you need to double click on the title bar which maximizes the window, regardless if maximizable is set to false, and then the buttons are usable.

maximizable is not supported on Linux and this behavior is documented
couldn't reproduce the other issue either (unusable buttons).
