Bad Quality on Raspberry PI

[zwick88]

Hi everybody,

if have build libvncserver and framebuffer-vncserver for Raspberry PI 3. We have an own RootFS without Desktop. QT Framework draws the Application GUI. My problem is that the quality is very poor or the images are partially consumed, although the client has set the quality to True Color

Here two Screenshots, one shows the bad quality and the other do good one.

Does anyone have a tip for me?
