Many thanks for these pointers!

I am aware that GLUT is somewhat outdated. But then - OpenGL as a whole is about to be spelled Vulkan today. The funny thing is that GLUT still works fine, and it fits the OpenGL Programming Guide quite nicely. This ~15 year old guide comprehensively covers OpenGL and window management. I'll definitely try GLFW and its Perl module. I'll also check out your X11 module and the Sandbox.

Installing OpenGL::Sandbox from CPAN on my Machine (Debian bullseye) gives one test failure:

Writing directly to a foreign buffer is not recommended at t/35-buffer.t line 39.

This might be an issue of my box because the CPAN Testers Matrix for OpenGL::Sandbox is clean.

BTW: I also tried OpenGL::Modern and was not convinced. It seems to cover "modern" OpenGL, but it needs some guessing around which export tags are needed for which interface, which interfaces are available and how interfaces using C pointers need to be rewritten. Plain old OpenGL comes with an examples directory which got myself started, the "Modern" thing has nothing like it, not even tests to steal from.
