If you use qt-5 (KDE) you can get nice alpha blended fonts if you set QPlatformIntegration::FontSmoothingGamma to 1.8. diff --git a/src/plugins/platforms/xcb/qxcbintegration.cpp b/src/plugins/platforms/xcb/qxcbintegration.cpp index 258359d20f28..8181aeaf5c8b 100644 --- a/src/plugins/platforms/xcb/qxcbintegration.cpp +++ b/src/plugins/platforms/xcb/qxcbintegration.cpp @@ -357,7 +357,7 @@ QVariant QXcbIntegration::styleHint(QPlatformIntegration::StyleHint hint) const break; // Not implemented, use defaults case QPlatformIntegration::FontSmoothingGamma: // Match Qt 4.8 text rendering, and rendering of other X11 toolkits. - return qreal(1.0); + return qreal(1.8); case QPlatformIntegration::StartDragDistance: { // The default (in QPlatformTheme::defaultThemeHint) is 10 pixels, but // on a high-resolution screen it makes sense to increase it.

And for them a gamma of 1.8 will make look fonts too light. You really have to use freetype's new CFF engine to get good results.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
