Hey there,
I’m in the process of building a little thing with a PiSound/Teensy and an OLED connected to it, but would like to do some prototyping first (testing different screen resolutions/sizes). Later on, it would be super-cool to re-use the GUI stuff I wrote in some way to the display via OSC. For now, requirements would be: Writing StaticText and drawing lines to a Qt Window and being able to change the DPI.
How would I go about doing that? I already tried to use Image.drawStringAtPoint, rendering single images to a QtWindow. Somehow, drawStringAtPoint doesn’t seem to work, I get this error:

^^ The preceding error dump is for ERROR: Primitive '_QImage_NewEmpty' failed.

trying to run the example from the Image.drawStringAtPoint help file.
I’m running SC 3.11.2 on macOS 10.14.6
Any help would be greatly appreciated! :~)
All the best,
