glarea demo in gtk4-demo broken
(gtk4-demo:22198): Gdk-WARNING **: 13:28:28.834: OPENGL:
Source: API
Type: Error
Severity: High
Message: GL_INVALID_OPERATION in glBindBuffer(non-gen name)
This only happens when using the OpenGL renderer (can't test Vulkan), but Cairo works.
Interestingly, tests/testglarea
also works. I guess this is because there are multiple toplevel windows that share the same GL context?
