I’m also experiencing this problem of size disparity between Dorico and all other programs/Windows itself. I’m on a Lenovo 15.6’’ Laptop with a display resolution of 1920x1080 running Windows 10. My scaling value is 150% to achieve good legibility in every program, but Dorico seems to interpret this value differently from every other application; I would need to set 100% for a usable scaling…
The previous versions behaviour actually made a workaround possible; I set Windows to a custom scaling percentage of 149% and Dorico would fit in by internally rounding to 100%. It would be great maybe to have an option to force a certain scaling factor for the program to compensate for (what appears to be?) an interpretation of the system scaling value by Qt that differs from that of other programs.
Best Regards
