GNOME installations have UI components without the edges or bodies.
I posted this issue on the GNOME OS GitLab but I didn't realize that this was a Boxes issue. I can't even log in for some reason, but this might just be something to do with my system. I run Arch Linux, the VM is Arch Linux, I use a Ryzen 7 5800X as a CPU and an ATI Radeon HD 4850 as a GPU. The GPU might also be the issue, as it is about 15 years old. I don't have these problems on my host system, also running GNOME.
