[amdgpu] Graphics corruption during modal dialog dimming on Xorg

[BertN45]

If I use xorg and Firefox asks for the master password that small window is unreadable and distorted. See the screenshot. If I type in the password blindly everything is working again. The problem does not exist with Wayland, but that one has another issue :(

Does this work around the problem?

gsettings set org.gnome.mutter attach-modal-dialogs false

[BertN45 (lammert-nijhof)]

No the gsettings did not help, also not after a reboot.
