QT 5.3.0 font problem when running application on qnx6.6.0

[rafael]

I have a test application with a button that just opens a file dialog.
it runs fine but all the fonts that get loaded are really small.
i am using vesabios for graphics and running virtual box on a windows host.

here is my start up script.

export GRAPHICS_ROOT=/usr/lib/graphics/vesabios
export QT_QPA_FONTDIR=/qt/lib/fonts
export LD_LIBRARY_PATH=/sbin:/usr/bin:/usr/lib:/lib:/lib/dll:/qt/lib:$GRAPHICS_ROOT
export QML2_IMPORT_PATH=/qt/qml
export QML_IMPORT_PATH=/qt/imports
export QT_PLUGIN_PATH=/qt/plugins
export QQNX_PHYSICAL_SCREEN_SIZE=1024,768

echo $LD_LIBRARY_PATH
echo $GRAPHICS_ROOT

repoen /dev/ser1
screen

i load my start up script and build the executable using QT creator.
it runs fine on virtual box apart from the fonts being really small.
