            Bug ID: 424254
           Summary: Mirroring internal laptop 4k screen to external 1080p
                    screen shows clipped output on external screen
           Product: kwin
           Version: git master
          Platform: Other
                OS: Linux
            Status: REPORTED

          Priority: NOR

Clipped output rather than scaled output

All KDE software built from source today on top of openSUSE Tumbleweed.

STEPS TO REPRODUCE
1. Have a laptop with a 4k screen
2. Set appropriate >100% scale factor in KScreen KCM (I'm using 250%)
2. Plug in an external 1080p screen via HDMI


OBSERVED RESULT
External screen shows only the top-left quarter of the internal screen. See
attached screenshot.


EXPECTED RESULT
external screen shows an exact mirror of the internal screen, but scaled to fit
rather than clipped.


ADDITIONAL INFORMATION
Reproduces both with and without PLASMA_USE_QT_SCALING=1 set in the
environment, so it doesn't seem to be related to that.
