Description Christoph Cullmann 2019-10-06 13:42:45 UTC 
SUMMARY

Using color theme chooser in e.g. Kate on second HiDPI screen with scaling => no further repaints/broken window

STEPS TO REPRODUCE
1. Open e.g. Kate
2. Move the Kate window to a second display with scaled output (e.g. scaling 2x) on X11
3. Select a color scheme in Settings -> Color Theme

OBSERVED RESULT

Window only shows artifacts, like in the "Konsole calls winId on non-native window" bug 411965.

EXPECTED RESULT

Color theme change.

This happens if you e.g. use the Fusion style, then all is fine.

SOFTWARE/OS VERSIONS

master build on X11, Qt 5.13.1

ensure winId() not called on non-native widgets

Summary:
if we do that, window will be corrupted

Test Plan: Use Kate, change color theme on a second screen with scaling
