Status of apps surviving Wayland compositor restarts

I remember reading about an effort to make it so apps can survive Wayland compositor starts. The necessary changes have been in KWin and Qt for 2 years now.

Did the necessary changes ever get merged into other GUI frameworks like Gtk, winit, etc? Can all (or almost all) my apps finally get this support?

Hi - there’s a wiki page on KDE Invent describing the overall process needed to implement that feature in a toolkit: Restarting · Wiki · Plasma / KWin · GitLab

That page has several links to work on other projects - the most current ones for the toolkits you mention seem to be:

Seems like it’s generally still pending some level of agreement on the approach, and then implementation work, in each of those.

Yeah. I was wondering whether that page is up to date, or whether there’s been progress with getting patches merged in the year since it was last updated.
