These two bugs had the same origin and was fixed by this:

> When one of the tabs/windows is affected by this bug, reloading the page fixes the problem.

> Another thing I observed (unrelated to this patch) is that AC only seems to work with cairo glesv2, if I use the cairo gl backend instead I see out-of-memory errors every time we try to paint the web view widget (the same errors I got when running AC on Wayladn with --enable-glx set btw).

I updated mesa/wayland to master and rebuilt everything from scratch and it all works fine now (both gl and glesv2, both with and without enable-glx), so that's good news :)
