Hey Paul,
Thanks for the new QT6 Dooble and new qos2.dll!. Window scaling and menu dropdowns now look great. It seems the fonts on the menu bar, tab, address bar and in settings are smaller than in the QT5 version though (I'm using the new DOOBLE_HOME environment variable to keep separate profiles), even though both are using Warpsans 9. Could there be a similar issue with font scaling as with window scaling?
Regards,
EDIT: attached a screen shot, QT6 on left, QT5 on right, both using Warpsans 9.
