    Description

      QComboxbox is too narrow causing its text to be clipped on screen that has non-integer device pixel ratio that is rounded down (tested on 4K screen under Windows 10 with native device pixel ratio of 1.5). See attached code.

       

      Bug was closed as non-reproducible under Qt 6.7, but test with Qt 6.7.1 shows bug still present. (see additional screenshot) Please test using Windows with device pixel ratio of 1.5.
