SUMMARY

SDDM security issue: I can see the session briefly for some time before unlocking 

I am using Manjaro 20.2.1 with KDE 5.79.0 / Plasma 5.21.1 on HP 15-bs164TU laptop. After I open the lid, I can see my previous session desktop and windows briefly for some time before the plasma locker screen appears. I had this issue on previous versions of Manjaro KDE as well.
