Description Michael Catanzaro 2022-03-23 14:20:38 PDT

With GTK 4, tooltips are sometimes broken. They usually work... except when they don't. Test by hovering over a link to a bug in this Bugzilla instance (e.g. the GTK 4 bug in the "Blocks" field up above).

When they don't work, they don't work for any link. When they do work,t hey work for all links.

Interestingly enough, when a tooltip fails, this happens:

```

OK, I'm running with G_DEBUG=fatal-criticals now to try to get a backtrace, but sadly the tooltips that were so broken for me yesterday are working just fine today. Let's hope I manage to catch it.

Ok, it's GTK. https://gitlab.gnome.org/GNOME/gtk/-/issues/5258

I had to give up on this due to https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1055. A fix for that issue was just released yesterday, but hasn't hit freedesktop-sdk yet.

I think this got mysteriously fixed at some point in the past year.
