2078254 - [Wayland][KDE-PIP] PiP windows cannot be moved after being double clicked

Status: UNCONFIRMED

(Core :: Widget: Gtk, defect)

Description

[[:LingM]]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:157.0) Gecko/20100101 Firefox/157.0

Steps to reproduce

Tested in a Plasma 6.7 Wayland session.
0. Set KWIN_WAYLAND_SUPPORT_XX_PIP_V1=1 in /etc/environment to enable the xx-pip-v1 protocol.

1. Start a video and open it in PiP mode.
2. Double click the PiP window.

Actual results

The PiP window can no longer be moved around.

Expected results

Usually double clicking the PiP window is supposed to turn on fullscreen mode. In a sense that appears to be exactly what happens. However, instead of filling the entire screen the window just refuses to be moved.

This is KDE specific Wayland extension.

Looks nsWindow::MakeFullScreen() it not even called for the xx-pip window.

Comment 3

[Martin Stránský [:stransky] (ni? me)]

Hm, so

nsWindow::MakeFullScreen aFullScreen 1
OnWindowStateEvent()
Fullscreen
AppWindow::FullscreenChanged(1) state 1

so it's called and Gtk tells us we're in fullscreen but we actually are not (at least for the PIP).

Perhaps the best solution may be to just disable the fullscreen for xx-pip for now as we'd need to plumb xdg-toplevel events to gtk events.
