<pre>I run Gnome on a tiled 4K display (meaning the monitor presents two 1920x2160
displays that are combined into an overall 3840x2160 display). When updating to
Fedora 25, I was finally able to run wayland in this configuration. However,
when doing so, the windows (and cursor) are scaled much too large. In X I use a
scale factor of 2x, but the wayland scaling appears to be at least 8x, possibly
more.
This is only an issue with tiled displays. I can also run my monitor as a
single 3840x2160@30Hz panel, and the scaling is normal there. Further, I have a
3840x2160@60Hz laptop that works as a single panel, and it acts normally.
Hopefully I'm filing this against the right product. Other bugs of this sort
seem to be filed against gtk's wayland backend, and I guess that's where the
scaling information is calculated? As I recall, changing the scale factors in
the tweak tool (which determines how things behave in X) has no effect when
this is happening, so I guess the wayland backed ignores that setting.
I'm running Gnome 3.22 (gtk+ 3.22.6). Let me know if any further information is
needed.</pre>
