+From: Fabian Vogt <fvogt@suse.de>
+Subject: Fix build against Qt 5.15
+
+With 0a93db4d82c051164923a10e4382b12de9049b45
+("Unify application palette handling between QGuiApplication and QApplication")
+QApplicationPrivate::setSystemPalette does no longer exist.
+
+This style does explictly not support "system colors" defined by the platform
+theme, which have priority over the style provided palette. To prevent the
+theme from overriding the colors, it previously used the system palette
+mechanism (which has priority over the theme), but that way does not work
+anymore. Instead, simply use QApplication::setPalette. While that has
+different behaviour and might break in some applications, it's better than
+having a completely messed up palette with certain themes.
+This is the same change as suggested by gamezelda on
+https://aur.archlinux.org/packages/qt5-styleplugins/#comment-749190.
