Deleting the settings file doesn't make any differnce but i just noticed this error when starting in terminal:
QStackedLayout::setCurrentWidget: Widget 0xc16fe0 not contained in stack do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly. Try adjusting the vblank_mode configuration parameter. libpng warning: Ignoring attempt to set cHRM RGB triangle with zero area so it seems to be an intel driver problem not an avogadro one.
