gsk: vulkan renderer breaks gtk4 apps on Raspberry Pi 4 and 400

On Fedora-Workstation-Rawhide-20240520.n.0.aarch64, gnome-initial-setup won't start on Raspberry Pi 4 and 400. This bug only happens with vulkan renderer. If I write GSK_RENDERER=gl or GSK_RENDERER=ngl to /etc/environment, gnome-initial-setup starts as expected and I'm able to finish the initial setup process.

However, when I switch back to vulkan renderer I'm not able to start any gtk4 app (such as nautilus, gnome-calendar, gnome-calculator, gnome-text-editor), gtk3 apps work as expected.

  • gtk4-4.15.0-1.fc41.aarch64
  • gnome-initial-setup-46.1-1.fc41.aarch64
  • nautilus-46.1-1.fc41.aarch64
  • gnome-calendar-46.1-1.fc41.aarch64
  • mesa-vulkan-drivers-24.1.0~rc4-1.fc41.aarch64

Steps to Reproduce:

  1. use arm-image-installer to create a bootable SD card
  2. insert the SD card into Raspberry Pi 4 or 400 and boot
  3. gnome-initial-setup won't start
  4. write GSK_RENDERER=gl to /etc/environment and reboot
  5. gnome-initial-setup starts, go through it
  6. change GSK_RENDERER in /etc/environment to vulkan (or delete the line) and reboot
  7. gtk4 apps don't start

The problematic functions seems to be gsk_gpu_box_shadow_op and gsk_gpu_color_op.
