https://www.kraxel.org/cgit/linux/log/?h=qxl-4.13 please test
Applied over vanilla 4.12 on top of the patch from comment #2.
SDDM started fine, I was able to login to the Plasma session and use it for some time. Test repeated twice with the same results. No errors found in dmesg and system is stable.
As for me - TEST PASSED
Thanks :)
