[Bug] Inability to focus a window that does not use a headerbar

[toudi]

Description

I discovered this recently when I installed budgie desktop on opensuse tumbleweed. Initially I couldn't figure out the reason and then I started comparing packages between fedora 37 and tumbleweed and I realized that what was different was in fact mutter. then I started googling some more and I discovered this bug report:

I'm only mentioning this because fedora 38 is about to be released and I think it bumps mutter release as well.

If you already know about this issue (though I haven't been able to find it here on github) feel free to close this bug report

Budgie version

10.7.1

Operating System

Opensuse Tumbleweed

Steps to reproduce the issue

1. Open two windows which does not use a headerbar. For instance vs codium or chromium or virt-manager
2. Try to select the window by clicking on it's title bar

It only works with headerbar-enabled applications - like for instance budgie control center or gnome calculator

Actual result

You cannot focus the window. You can only focus the window by clicking on it's content area

Expected result

Being able to focus the window

As a workaround, certain things can be run with the environment variable GTK_CSD=1 to mitigate this.
For example, running GTK_CSD=1 virt-manager will get you a clickable title bar at the expense of forcing client side decorations. Doesn't work with everything.

I don't really like it, its bandaid over an ugly issue, but there you have it.
