Implement fake mode-setting using wp_viewporter
Submitted by Robert Mader
Assigned to Wayland bug list
Tracker bug for the experiment to implement fake mode-setting for xwayland. The idea is to not really set the mode but to make clients believe they can and to scale their output accordingly.
The main motivation is to work around the fact that a lot of legacy applications, especially proprietary ones, don't support different screen resolutions and therefore fail to start in xwayland. This is a regression for a number of users, potentially preventing them to switch to wayland-based compositors (e.g. using gnome-X11 instead of gnome-wayland).
