@piotr (peterq94) refer comments #22 & #24 on this report. I've written about this (work-around) on Lubuntu's discourse I believe too (https://discourse.lubuntu.me/t/login-screen-flashes/1634/7 and maybe elsewhere too). I've lost access to the d990 (which wasn't my box) so I can't test further with it.
There are other bugs relating to sddm flashing (non-nvidia graphics) which can likewise be mitigated as this was.
