Schema changes need to be manually "installed". I don't remember the
syntax but it doesn't really matter. Just try changing the setting
manually:
gsettings set org.gnome.mutter workspaces-only-on-primary false
But that's not really important either right now, because changing the
setting
Hello @vanvugt,
I manually edit workspaces-only-on-primary false in
/usr/share/glib-2.0/schemas/10_ubuntu-settings.gschema.override
/usr/share/glib-2.0/schemas/00_org.gnome.shell.gschema.override
Followed the steps in the bug description, my screen freeze after the external
monitor plugged.
Figured it out: The bug only happens with:
org.gnome.mutter workspaces-only-on-primary true
which is only set in GNOME sessions because:
/usr/share/glib-2.0/schemas/10_ubuntu-settings.gschema.override
/usr/share/glib-2.0/schemas/00_org.gnome.shell.gschema.override
You can avoid the bug
Also the bug seems to be GDM-specific. It never happens if you launch
'gnome-shell --wayland' manually from a VT. Even the same binaries.

General steps to reproduce the bug on any jammy system:
0. Find a single display machine that you can attach a second monitor
to.
1. Disconnect all secondary monitors so you only have one screen.
2. Log into a Wayland session.
3. Open the Extensions app and disable Desktop Icons NG (DING).
4.
Tested #58, issue couldn't be reproduced on my Tributo UHD panel + 4K external
monitor.

Based on comment#57, I built a test deb for this issue. If anyone wants
to test the patched gnome-shell-extension-desktop-icons-ng, please refer

I will keep working on a mutter fix, but we're no longer blocked waiting
for it. Regular app windows can get stuck in the same kind of infinite
loop so we should figure out a test case in that style before

I have a workaround/fix for DING that works. But before I propose that
I'm going to see if I can fix mutter still. It seems the problem is more
fundamentally in mutter, though they are fighting.
Roughly the problem is:
1. DING creates a fixed size window the size of the monitor. But it always
