I don't understand how to fix it.

v 3.9.0, videodriver GeForce GameReady 527.56

@Seliverstoff I found a solution to the problem. In the nVidia control panel, you need to force it to use the nVidia processor for DesignStudio. For some reason, by default, the built-in processor tries to draw graphics, and this leads to errors.

Hi, and welcome! Thank you for sharing your solution.

Is your default GPU an Intel one? Intel integrated GPUs are known to cause various problems, especially when combined with a dedicated NVIDIA/AMD GPU (for example: https://bugreports.qt.io/browse/QTBUG-69538 )

Yes, that was exactly the problem. I also updated the intel graphic drivers. In this case, the nVidia panel settings are not required.
