only a grey window displayed on Mac

[klauspdoll]

This example works for me on openSUSE15.5.

I would however be interested on a working version for Mac also.

Some time ago, I could build it on a Mac Monterey, and it was okay (shader version 410 was necessary, as reported in https://github.com/ebassi/glarea-example/issues/9). Most likely because of an update which happened meanwhile when doing brew install glm (glm was required by some code using the OpenGL core profile), it now still compiles, but shows a grey window only. On an older MacBook I have access to (with renderer Intel Iris Pro OpenGL Engine), it is the same (grey window); also other people reported a grey window on fairly new Mac M1 .

Is there any workaround known for this?

You should file an issue on the GTK issue tracker.
