There is no scanout hardware connected to the AMD GPU, so if there is any involvement by amdgpu it is purely by making i915 misbehave.
This is also not a GNOME bug - the display corrupts as soon as the KMS driver is loaded, which, since I've got an encrypted rootfs, is early in the initramfs. The same behaviour is observed regardless of the kernel commandline options, too, so it's not plymouth doing something weird, or vthandoff. It also happens with break=mount.
