[Pkg-chromium-maint] Bug#790712: chromium: Reacts poorly to changes in dpi after suspend and resume

[Dylan Thurston]

Package: chromium
Version: 43.0.2357.130-1
Severity: minor

Minimal sequence to reproduce:

% xrandr --dpi 200
% chromium &
<suspend>
<resume>

In order to work around bug #789213 ("HiDPI mistakes with xfce4
again") under xfwm4 version 4.12.3-1, I ran "xrandr --dpi 200" before
starting Chromium. After suspend and resuming, Chromium behaves very
strangely with respect to the mouse: a mouse click registers for
chromium some distance to the upper-left (varying depending on the
precise position). The mouse pointer shape also changes accordingly;
that is, the mouse pointer will change to a text insert symbol if the
relevant point to the upper-left is a text input field.

Note that the display resolution is reset to 96 dpi after suspending
and resuming, for some reason I haven't tracked down. However,
manually changing the dpi with xrandr does not cause strange
behavior.
