Bug Description

I have the BQ E4.5 and it's working better that MX4.
MX4 has lags moving sprites in games (as Panda Love), in the apps scope, even in the camera.
With its hardware, it should works a lot better, then I think the drivers is not perfect for this model (?).
Thanks a lot in advance!

I'm also finding my MX4 incredibly slow, occasionally. Ususally, things are running along smoothly, but every now and then, everything freezes for seconds, typing is delayed by at least 1-2 seconds, app-loading, forget it...

I've managed to switch to terminal during some of these events and, in "top", seen dbus-daemon consuming a LOT of CPU at these times. (>50% CPU). With 4 days uptime, I see dbus-daemon have consumed 294 minutes (almost 5 solid hours) of CPU-time. A LOT more than, for example unity. Also, during regular light use, dbus-daemon is consuming ~2% CPU.

Is there any easy way to run dbus-monitor in the background, saving to some compressed file, in order to see what type of messages are produced over a period of time?

@costales I think its mainly due to the higher resolution and the quality of the graphics driver
@Ulrik we are chasing that dbus issue, it has something to do with wifi scanning but we cannot nail it yet
marking this incomplete since not sure what to do with it, there are other more specific bugs logged elsewhere
