            Bug ID: 433867
           Summary: Icons on secondary screen move around on boot / wake.
                    Possibly because of screen rotation
           Product: plasmashell
           Version: 5.20.5
          Platform: Gentoo Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: Multi-screen support
          Assignee: aleix...@kde.org
          Reporter: rich...@qweb.co.uk

  Target Milestone: 1.0

SUMMARY
My laptop, an ASUS US563F, includes a secondary screen under the touchpad. The
screen is at a 90 degree rotation so within KDE's own display configuration, I
have the orientation set to a 90 degrees anticlockwise rotation.

KDE picks this up just fine and rotates properly once I'm logged in, although
SDDM shows unrotated upon initial boot which is understandable if the display
config is user specific, but if I place icons on this screen, they're shuffled
to seemingly random locations every time I boot up, or close the lid and
re-open, or fold the lid back and reset to a natural position. Each of these
events effectively turns the screen off and back on again so presumably it's
the power-on event that triggers this shuffle.

My feeling is that KDE is setting the icon locations first, then actioning the
rotation, and having to shuffle icons around to fit the new orientation.
Swapping these two events so as the rotation happens before the icons are
loaded would I'm sure resolve.

STEPS TO REPRODUCE
1. Add icons to a secondary screen with a 90 degree orientation.
2. Reboot, or close the lid and re-open if a laptop, or probably just reconnect
the secondary screen.
3. Compare the icon positions to their original.

OBSERVED RESULT
Icons move around to seemingly random locations each time the screen is
reconnected.

EXPECTED RESULT
Icons shouldn't move around on their own accord.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 
KDE Plasma Version: 5.20.5
KDE Frameworks Version: 5.77.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
Gentoo GNU/Linux on an ASUS UX563F laptop with a secondary screen permanently
attached under the touchpad device.

I've experienced this bug since originally setting this laptop up probably 6
months or so ago. Unsure of the KDE versions in use at that time but this
certainly isn't a new issue to the above versions.
