<pre>Gustavo found the cause of the split image, and it's a bug in GTK+: <a href="https://bugzilla.gnome.org/show_bug.cgi?id=771060">https://bugzilla.gnome.org/show_bug.cgi?id=771060</a>
Given that AC was not available under Wayland I would suggest to disable it if Wayland && HiDPI && GTK+ < 3.22 (assuming a fix will land) are detected rather than preserving the glReadPixels() codepath, I don't think it's worth carrying it for what I suspect is a case that nobody will ever encounter.</pre>
