We (VICE), have a longstanding problem with GtkGlArea failing on Intel GPU’s. Especially on Windows, which unfortunately is most of our users.
Is there some workaround for this, except using Cairo, which we currently request our users select as a fallback. Gtk (epoxy?) reports it supports OpenGL 3.2+ with Intel chipsets (specsheets usually indicate much higher OpenGL standards), but either realizing a GtkGlArea either immediately fails or it runs for a few minutes and then segfaults.
Has anyone had similar issues?
