>From that it looks like the LCD is 1024x600, so the issue you're seeing
is the existing demo applications are currently hard-code to assume a
resolution of 1920x1080.  In releases prior to the switch to
agl-compositor in Jellyfish, the applications did have some simple
scaling code, but it was decided that supporting that going forward
wasn't required.  So you'll need to hack on the QML of the applications
you're interested in to scale them for your display.  I suspect that will
help with the input issues as well.
