Hi Yuuki,

The stretching issue seems a Gnome/Mutter issue, because other GTK
applications have the same problem.
But that the text becomes blurry only happens to the pgtk port.

I don't think three monitors are needed. Two monitors, one scaled <at> 2x
and one @1x, should be enough to reproduce the issue.

That said, I'd love to help debug this issue on my end, but I don't
know what to start with. Any ideas?
