Actually I didn't find any request for 32-bit RGBA in the example... Neither in the doc about QPainter, QOpenGLWidget nor QOpenGLWindow. Unless I missed something?

Just in case, I removed the format request in the main(): so basically now I get whatever the OS will give me by default.

But it still crashes...

Also I may not have the hand on the machine running the program - it may be a customer's machine far, far away in a distant... well you get the idea.
