Hello, the bug is reproducible, but wondering because such scaling issues should have been resolved upstream in the Qt library itself, please see: https://bugs.kde.org/show_bug.cgi?id=391694 https://bugreports.qt.io/browse/QTBUG-67007 Checked also to set the scaling to the next integer, 2 to see if it matched the bug before. It does, there is no trouble as soon as the scaling is an integer. But when it's a fraction the rendering is broken. But due to that additional the layout breaks I think it is not a duplicate, I'll link the issue 391694. Or what do you think, is this a duplicate? maybe it's related to another Qt bug reported by Kai some hours ago https://bugreports.qt.io/browse/QTBUG-70481 Here's the deal: The first attempt at fixing this upstream (https://bugreports.qt.io/browse/QTBUG-67007) failed and made the problem worse. We now have two options: - Fix it upstream correctly (tracked by https://bugreports.qt.io/browse/QTBUG-70481) - Work around it in KDE-land by using QtRendering instead of NativeRendering. This happens automatically for UIs that use QQC2 due to our theming. I suspect the issue is QQC1 controls here. Git commit 894f6706afeff7fff73ad0afe4cbf90dfe9b0387 by Björn Feber.

Created attachment 114888 [details] screenshot Set display scaling factor to 1.2 in system settings > display and monitor. Restart plasma session and open plymouth kcm. My screenshot taken on neon dev unstable shows the result.
