Since the release of wayland-protocols 1.7, a new xdg_shell v6 is introduced[1]. This breaks backward-compatibility with older xdg_shell implementation. [1] https://lists.freedesktop.org/archives/wayland-devel/2016-August/030606.html Reproducible: Always Steps to Reproduce: 1. Wayland-protocols 1.7, wayland 1.12, and weston 1.12 need to be installed. 2. Launch weston-terminal app on plasma wayland session or kwin_wayland Actual Results: Notice that weston-terminal can't be launched, with the following message weston-terminal: clients/window.c:5118: window_create_internal: Assertion `custom || display->xdg_shell || display->ivi_application' failed. Expected Results: Kwin_wayland is able to launch weston-terminal and other weston apps. This issue doesn't occur on Gnome 3.22.1, since weston-terminal and other weston apps run fine on Gnome 3.22.1
will this enable native wayland gtk3 apps ander kwin?
Implemented as of 5.39 release. Also integrated into KWin/master, so Plasma 5.12 will support this.
