Steps to reproduce: * Have an external monitor connected (set as primary screen in Gnome 46.1) * Create an Epiphany Desktop-Web-Application from a website * Open Desktop-Web-Application (it gets opened on external monitor) * No content is rendered * Error message: `Apr 22 14:52:49 sv15 org.gnome.Epiphany.WebApp_2ced57f125910a9e8ab95deea86e4ad7be418b5a.desktop[9934]: Failed to create GBM buffer of size 0x0: Das Argument ist ungültig` Workaround: * Move the window to laptop screen and click "New Window" * A new window is opened on the laptop screen and content is rendered (no error message in log) The error message is the same as mentioned in https://bugs.webkit.org/show_bug.cgi?id=265154 - but the cause seems different. I have raised an issue with Epiphany here: https://gitlab.gnome.org/GNOME/epiphany/-/issues/2302 and verified that I have `webkitgtk 2.44.1-1` installed. OS: Arch Linux
