I would consider this a Qt (documentation?) bug: "The application attribute Qt::AA_DisableHighDpiScaling, introduced in Qt 5.6, turns off all scaling. This is intended for applications that need to use actual window system coordinates, regardless of environment variables." It explicitly mentions the env variables but yeah better safe than sorry, I guess KWin and KRunner need the same treatment. - Kai Uwe ----------------------------------------------------------- This is an automatically generated e-mail.
