Transform is set in
https://cgit.kde.org/libkscreen.git/tree/backends/xrandr/xrandroutput.cpp#n392.

Normally this is set to identity matrix, but if one output is replicated it
might be set differently such that the output fits the into the replica.

If you have some manual scripting going on you can try to reapply it after
KScreen daemon has done its work.

In general KScreen can't respect manual scripting and will just override such
efforts when it applies its own settings via X11 protocol.

What could be a goal is to allow setting the scale individually for outputs in
KScreen via transform matrices. But it's not on my priority list right now.

Btw to make matters worse, the panning areas of the 1080p displays are not
reconfigured accordingly after scaling is reset to 1.0, so when I move the
cursor around they sometimes show empty framebuffer areas.
