Public bug reported:

I have a dual monitor setup with Nvidia Geforce GT1030. The card has a HDMI and 
a Display port output. Both displays are attached to different monitor brands 
with the same resolution. Gnome apps scale the same on both displays, but some 
QT apps like Backintime 1.2.1 or rstudio 1.2.1 have different scales on both 
displays.
Scaling changes when apps are moved on the desktop from one screen to the other.

Title:
  QT apps have differing scaling on dual monitor setup

  New

Bug description:
  I have a dual monitor setup with Nvidia Geforce GT1030. The card has a HDMI 
and a Display port output. Both displays are attached to different monitor 
brands with the same resolution. Gnome apps scale the same on both displays, 
but some QT apps like Backintime 1.2.1 or rstudio 1.2.1 have different scales 
on both displays.
  Scaling changes when apps are moved on the desktop from one screen to the 
other.
