+From c3eeb421526f284419e90d2c4c4da5b0d7bbcc0e Mon Sep 17 00:00:00 2001

+Subject: tdf#124292 Qt5 / KDE5 disable Qt's HiDPI scaling
+
+LO does its own layouting and also all the scaling, so disable
+the automatic HiDPI scaling explicitly. Otherwise fonts will be
+rendered in LoDPI and just scaled as an image, if UI scaling is
+enabled in KDE, resulting in really blocky / ugly fonts.
