The default is the "raster" graphics engine, which works somewhat like you described in your original e-mail: http://labs.qt.nokia.com/2009/12/18/qt-graphics-and-performance-the-raster-engine/ The "native" graphics engine uses regular X11, which will probably always be best over SSH. Qt also respects the QT_GRAPHICSSYSTEM environment variable to configure this, so you can add `export QT_GRAPHICSSYSTEM=native` to your ~/.profile or wherever to make it your "default". -T.C. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
