I develop a GTK application. On the host it runs fine, but on Flatpak it sometimes has short ~0.3 s freezes of the UI that I’d like to diagnose. I’ve tried recording it with sysprof (both within Builder and with
sysprof-cli --gtk --use-trace-fd -- flatpak run --devel my.application.Here), but
org.gnome.Sdk seems to be missing counters so I can’t tell when the freezes actually occur in the recording, and I don’t see anything odd in the backtraces as is. How can I diagnose issues like this?
org.gnome.Sdk//3.38 and can build the application inside and outside of Builder. I’m on Fedora 33, Wayland.
