Follow-up Comment #126, bug #49053 (project octave):

Welp, that was a crazy easy fix! It appears that the redraw was getting
triggered before the screenChanged signal was triggered. My simple solution
was to just request a redraw in the screenChanged event handler.

Just to be safe, I also did a redraw request it at when the windowShown event
is triggered and we update the devicePixelRatio in that function.

See the attached diff patch (I really tried this time to get the formatting

(file #44041)
