            Bug ID: 398123
           Summary: When reconnecting a second screen, what is displayed
                    is friezed
           Product: KScreen
           Version: 5.12.2
          Platform: Mageia RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: common
          Assignee: sebas@kde.org
          Reporter: yves.brungard_mageia@gadz.org
  Target Milestone: ---

I use a laptop with a second screen connected over HDMI. Both screens use
1920x1080 resolution.
I get sometimes weird situation where the second screen displays a normal
screen (windows or lockscreen) but what it displays is friezed. However all
seems to be active, I can for example slide window from the second screen to
the first one.
Clicking with the mouse has expected behaviour, except that I do it blindly. It
seems that I have a mask on the second screen.
This happens when I disconnect and reconnect the second screen with a suspended
session period in between. There is other cases when this happens, but I'm not
sure of the circumstances.
I didn't find any error reported in journal.
Which information can be found to help the debugging?
