STEPS TO REPRODUCE
I don't remember exactly how I ended up like this. I think I have set 125% scaling because FullHD at 100% was too small on my 13" screen.
Then I tried to go back to 100% but still got big fonts, hence also manually overrode font DPI to 96.
However now the settings menu is showing this mismatch between the selected resolution (1920x1200) and the one in the "layout preview" area.
This mismatch is staying there even if I change resolution, restore some custom scaling, toggle font DPI between 96 and 120dpi...basically none of the fiddling around I've tried seems to remove this weird resolution.
OBSERVED RESULT


EXPECTED RESULT
If 1920x1200 is selected from the dropdown, the layout preview above should display that resolution, not 1536x960

Well 1920x1200@1.25 is 1536x960, so the resolution is correct in fact after the scaling.

From a user perspective we might want not to match the logical size of the screen, and this would be a usability improvement.

What strikes me more, is the fact that the global scale progress bar is not at 125%.

Please not that global scale changes are only taken into account after a deconnection/reconnection under X (with Wayland it is directly applied).

Do you still the UI discrepancy after a deconnection/reconnection ?
