During most resumes from RAM I see a display with black screen & some corruptions for a 1 second or less.

This is *not* critical but since it's a tracked regression I decided to report it with a hope it's something easy & possible to fix. After that second (or less) displays shows an expected image (KDE lock screen) and everything works normal afterwards.

This problem still exists in the 5.0.0-rc3.
