Hi Oliver. Thanks for the reply. At the moment our example is just "compile qnanopainter" since it's what gave us the radically different results between 5.9.x and 5.12.x in the first place. Just in case I've also opened an issue in qnanopainter because something can be off there too. I remember the library had issues on Win back in the day.
I'll try to create a decent minimal example asap and create a bug. F.
