GtkGLArea doesn't work with Nvidia + GTK4 + X11
GtkGLArea doesn't work specifically with Nvidia + GTK4 + X11.
My GLArea just shows "Unable to create a GL context". But the same GtkGLArea logic works with GTK3 on the same Nvidia system. And the same logic works with GTK4 if I change from Nvidia to Intel graphics.
BTW I use GLES: gtk_gl_area_set_use_es (GTK_GL_AREA (gl_area), TRUE);
