cmake-gui with oversized fonts

I have a screen which requires me to use 1.25x scaling. I achieve this by setting 1.25 text scaling coefficient in gnome-tweaks. In Fedora 26, this scaled Qt5 apps correctly (such as cmake-gui, kstars, VirtualBox etc.). After installing 28, text in Qt apps appear to be scaled in excess (see screenshot attached). Note that the problem does not occur for scaling 1.24 or less, but then many other applications do not look as desired (particularly Opera), so I'd rather use 1.25 scaling. I tried tweaking QT_AUTO_SCREEN_SCALE_FACTOR and QT_SCALE_FACTOR environment variables but I could not make the interface font smaller (I only succeeded in making it even larger). I have noticed that running:

echo 'Xft.dpi: 96' | xrdb -merge

helps to solve the issue for the current session, but I don't know how to make this setting permanent, since after restart it reverts to old setting (120 = 96 x 1.25):

$ xrdb -query | grep dpi
Xft.dpi:	120

Please fix this because it broke all Qt5 (not sure about Qt4) apps which worked perfectly before (at least in F26) :(

Re-triaging to qgnomeplatform (assuming this may be specific to Qt5 running on gnome)
