Whoops, There's A Big Problem For Wayland GTK+
Phoronix: Whoops, There's A Big Problem For Wayland GTK+
It turns out there's a rather serious issue for some systems when having Wayland support within GTK+ exposed, which may hinder the Wayland GTK+ availability in the near-term...
It doesn't sound like this has anything to do with Wayland
It's Cairo and the way GTK is using it that's the problem. It just so happens that Wayland requires that to be used, but nothing about Wayland in particular is actually causing this.
