I've done a lot of changes to how the glarea works and how the internal gl machinery works. I'm seeing a lot better performance than this, can you try it again and see how the current code performs? > I also see rendering locked at a sub-multiples of 60fps - despite the > fact that the rendering is additionally synchronized with the compositor > frame clock.

How exactly do you see this? _______________________________________________ gtk-devel-list mailing list gtk-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-devel-list
