xfce4-session-gtk3 upgrade from 4.13.3-1 => 4.13.3-2 breaks login/ui
Sorry for sending this report already by mail, but I just stumbled across the Gitlab repository afterwards:
Upgrading xfce4-session-gtk3 from 4.13.3-1 to 4.13.3-2 results in the desktop to appear with flickering colour distortions and only showing the xfce-panel but nothing else (Rendering the UI unusable).
Downgrading this package to the previous version resolves the issue.
Hardware configuration: AMD Ryzen 2700X AMD Radeon Vega 64 with open-source amdgpu driver
If there are any relevant logs or configuration files which I can provide just let me know.
