<pre>Somewhere between c93efb0a4f and 1edc53a66b a regression was introduced,
causing SDDM launching into a pure white screen instead of the login screen.
There's nothing logged to either /var/log/Xorg.0.log or /var/log/sddm.log and
dmesg is also clear. Downgrading to c93efb0a4f lets me login again.
I have not bisected yet, but maybe this information is already enough to find
the cause. For the full stack affected by this regression, please see below.
