libEGL warning: DRI2 failed to authenticate on Raspberry pi

  • Hello. Im running Qt Creator 4.11.1, Based on Qt 5.14.1 (Clang 10.0 (Apple), 64 bit) on my Mac, developing a GUI intended to run on my Raspberry Pi Pi Zero W running Raspbian Buster 2020-02-13. Im using python to interact with my .ui script.

    Running my script I get these errors

    libEGL warning: DRI2: failed to authenticate
    qt5ct: using qt5ct plugin

    After googling and researching about this for hours, I cannot find a solution or fix. I've tried following this with no progress.

    The main issue with my application is that the stylesheets are not loading properly. Specifically the opacity part of rgba(0, 0, 0, 0). Other than that it seems to work ok.

    Is there a fix or a workaround? I just want my GUI to run and look all pretty like I've designed it. It runs great on my Mac, and I want it to look the same on my Pi. I cannot get it to run on my Pi 3b+ either.

    Please help, I've been working on this project for a long time.

    Best regards,
