--- Comment #2 from Pekka Paalanen <ppaalanen at gmail.com> ---
Have you checked that the Wayland compositor actually is configured to have
output scale 2? Or that it is not deliberately showing X11 windows unscaled
because some X11 toolkits might do hidpi in secret and you don't want to scale
up twice?

If X11 apps cannot indicate in which scale they render, then I'd assume
Xwayland has no other choice than to use buffer scale 1. When the Wayland
compositor is configured correctly, it will scale up all X11 windows. The
downside is that Xwayland cannot support hidpi apps. So, you'd have to somehow
get that scale info from X11 apps to have them not scaled up twice. Is there
any X11 protocol for that?

I gave a quick try with Weston and xterm, and output scale 2 causes the xterm
to be scaled up like you would expect.
