Title
Mir input events support key-repeat state. QtMir isn't passing this to the
shell however, and thus not passing it to client.
QtUbuntu probably also needs to support the same.

There's not enough information here to make a proper attack on this
issue, and this is a complex topic.
We need someone to sit down and determine things like:
1. why did the OOM killer strike a foreground app? Did it use an insane amount
of memory? If a webapp, is it a QtWebkit-based app, or

Title:
Stretched frame after rotation issue in TimeDate page of System
Settings
@mardy looks like your shell does not have the correct values for
DBUS_SESSION_BUS_ADDRESS and UPSTART_SESSION. These commands will try
fetch those values from the unity8 process:
export `xargs -n 1 -0 /proc/$(pidof unity8)/environ | grep
DBUS_SESSION_BUS_ADDRESS`
export `xargs -n 1 -0
I'm still struggling to reproduce this. Another suspicion I have is ibus
being loaded. Could you do
stop unity8-dash
initctl unset-env --global QT_IM_MODULE
start unity8-dash
and see if that makes any difference. Thanks
