    Okay, so to clarify - all your tests from previous post was done through VNC?
    Did you try running your Qt app on local VirtualBox machine?
    I would like to be a "Guru"

    Useful hints (try them before asking):
    1. Use Qt Assistant
    2. Search the forum

    If you haven't found solution yet then create new topic with smart question.

    Sorry for long silence. I resolved the problem by typing "xhost +SI:localuser:jenkins" and using "-platform minimal". Thank you all for your help!
