Bug#940556: gnome-terminal: uses DPI from wrong screen resulting in hard to read font rendering

[Ansgar Burchardt]

Package: gnome-terminal
Version: 3.34.0-1
Severity: normal
Tags: upstream

I have a laptop with an external screen; internal and external screen
have different resolutions and DPI.

Since a recent update gnome-terminal and other GNOME applications use
the DPI from the wrong screen when the window in located close to the
screen boundary.  (In particular it seems to be triggered by the
shadow around the window reaching the other (left) screen.)  This
results in hard to read text.

I've seen this happen with gnome-terminal and gnome-settings under a
Wayland GNOME session; not with emacs or firefox (which still use X as
far as I know).  I've installed gnome-shell 3.34.0-1 and a few other
packages from experimental to give them a try.
