Bug#1096033: libgtk-4-1: first startup of programs depending on libgtk-4-1 4.17.4+ds-4 very slow, often lagging minutes

[Markus Steinko]

Hi there,

I am facing the same bug on a Debian testing system, running Gnome.

Many applications are just reacting very slow. Like gnome-terminal, 
gnome-settings, gnome-tweaks and the extension-manager. Also some are 
loosing their dark-mode and turn back to light mode...

It's not an extension that causes the error and resetting the system 
with "dconf reset -f" did not help.

Using  mate, or cinnamon desktop environment is a temporarily solution 
for  me.

It started after installing these updates this morning:
