Windows: High DPI scaling is rounded to nearest integer

    XMLWordPrintable

Details

    Description

      Application with Qt::AA_EnableHighDpiScaling and dpiawareness=2 seems to round scale factor to nearest integer. For example, 125% is same as 100% and 150% is same as 200%.

      With native applications, like notepad, each scaling factor seems to scale everything (menus and content). In Qt applications, only window title seems to be affected when switching between 100% and 125%.

      It seems to work fine with dpiawareness=1.
