    Details

    • Platform/s:
      Windows

      Description

      When Qt::AA_EnableHighDpiScaling flag is set, and screen scaling is set to 200% (as recommended) loading fonts via FontLoader dynamically (e.g. via StackView) causes warnings printed and improper font rendering.

       
      Application output:

      QWindowsFontEngineDirectWrite::addGlyphsToPath: GetGlyphRunOutline failed (The parameter is incorrect.)
      QWindowsFontEngineDirectWrite::addGlyphsToPath: GetGlyphRunOutline failed (The parameter is incorrect.)
      QWindowsFontEngineDirectWrite::addGlyphsToPath: GetGlyphRunOutline failed (The parameter is incorrect.)
      QWindowsFontEngineDirectWrite::addGlyphsToPath: GetGlyphRunOutline failed (The parameter is incorrect.)
