KDE Desktop -- Screen repaint does not happen after password (screensaver/locker)

I have been running Leap 42.1 for a while. And I run two monitors, one DVI the other VGA.

I had been hoping that a fix for this would just show up in Yast with me putting on fixed every week or so, but, no.

Once I get a screen saver lock to take place, I will enter my password & <enter> and the monitors go black. They show they are getting signal, but black.

Then if I move the mouse, bits and pieces of windows that are in use start showing up. If I grab TBird and fling it back and forth between the two monitors, everything will repaint.

Sometimes, if I touch the right window (as in correct, and who knows why it is the “correct” one), both monitors show the windows open on them.

Didn’t have this problem with SUSE 13.2.
