+Subject: [PATCH] xsettings: Round the Xft.dpi setting to an integer
+
+When using gnome-tweaks to set a text scale factor that is not a
+multiple of 0.25 (e.g. 1.1), Xft.dpi would be calculated as a
+floating point number, which breaks the fdo spec:
+
+https://www.freedesktop.org/wiki/Specifications/XSettingsRegistry/
+
+Although GNOME could handle the floating point Xft.dpi, graphical
+programs restrictively followed the above-mentioned spec would be
+influenced negatively. For example, QT applications (running on
+GNOME desktop) may ignore text scaling factor when Xft.dpi was
+calculated as a floating point number:
+
+https://bugreports.qt.io/browse/QTBUG-64738
+
+The patch at the same time has few impact to GNOME itself.
