    Description

      See QTBUG-40277 QTBUG-41102 QTBUG-49374 QTBUG-46615

      All styles are currently subject to rounding errors for small items (frames, etc) when High DPI scaling is in effect. Ideally, all styles code (metrics, drawing) should use qreal instead of int.

      This might affect the planned source code compatibility of Qt 6, though.
