I'm running Fritzing on a Panasonic Touchpad tablet, FZ-G1, under Linux 64 bit. All was working fine, but I've done something and the resolution when I start up Frizting is way larger than the screen.
This work QT_AUTO_SCREEN_SCALE_FACTOR=0 ./Fritzing to bring it back in line with the tablet.
The resolution of the tablet is set at 1440 x 900.
