KDE: we have compositor crash recovery in testing
I've been using GNOME on Wayland for over 5 years and I can't recall it ever crashing. Hangs and freezes, yes, but not a full crash. I guess the fact that users feel the need to track "crash recovery" as a feature is indicative of KDE's stability.
That has nothing to do with Slack's screen sharing issues. Screen sharing was broken due to Electron bugs and it's fixed in Slack 4.34.
Many Electron maintainers are Slack employees. They're contributing upstream more than most other companies that use Electron, especially compared to their size.
The issue is that 13 is not divisible by anything, so we can't split the year by halves or quarters like we do now.
