The bug seemed to appear after upgrading to GNOME 49.

OS: CachyOS x86_64 (Linux 6.16.8-2-cachyos) Desktop Environment: GNOME 49.0 GTK3 version: 1:3.24.51-1.1 GTK4 version: 1:4.20.2-1.1

Have someone made a fix or workaround?

Have someone made a fix or workaround?

I've just been using the CLI in the meantime...

[syorito-hatsuki]

Same here. Starting Windows laptop instead of Gnome right now just because of that (I no clue how right use CLI)

I use Arch Linux

[ahnafhabib992]

On Arch Linux use gdk-pixbuf2-noglycin from the AUR instead of gdk-pixbuf2 from the Extra repo.

[rajayonin]

Have someone made a fix or workaround?

Someone also mentioned in the AUR repository that running it with sudo makes it work. It does work for me (I'm using Arch), as well as what @ahnafhabib992 mentioned of using gdk-pixbuf2-noglycin.

[yochananmarqos]

....running it with sudo...

How about.. NO.

[ungaul]

On Arch Linux use gdk-pixbuf2-noglycin from the AUR instead of gdk-pixbuf2 from the Extra repo.

~~THIS is the fix for people in GNOME 49!~~

EDIT: while it fixes the issue, it also break every GNOME icons systemwide, so DON'T!
