HiDPI users might have experienced seeing a tiny UI window after installing Insync.
Please make sure to run this command on your terminal: QT_AUTO_SCREEN_SCALE_FACTOR=1 insync start
Just in case the font size is too big for you, run QT_SCALE_FACTOR=[INTEGER] instead. Then you can adjust [INTEGER] accordingly.
If this doesn't work for you, shoot us an email at support@insynchq.com
