Gnome Music uses a ridiculous amount of CPU when doing nothing

This is just when it's idle: http://i.imgur.com/ZcytEOF.png

Any idea what could be going on? I've never seen PyGTK work this poorly under any circumstances...

Actually playing music seems to make no difference in the CPU usage, since mp3 decoding is so negligible on modern CPUs...

Uh...I dont know if it is just me, but nothing seems that wrong based on your screenshot...

I think it would be a good idea for you to show us the process for Gnome Music.

Another note: I know I'll get reprimanded for this, but it's strongly recommended that you do not run chromium or other web browser under root. You don't want a hacker getting complete control over your computer....

Actually, it's not even possible to run chromium as root. Unless you're using some unspeakable hacks, that is. Most likely, OPs setup is beyond all repair at this stage.

I thought you can run chromium using another folder as the user directory? I also browsed the web with the --alternative-user-dir command flag when I reached post-install stages of my system. I didn't know the was a general precaution until I reached the wiki here. They must have updated chromium if hacking is the only way to get it running.

Ouch, guys!

For what it's worth, I think lxtask actually misreports chromium as being run under root -- it does the same for Opera on my Ubuntu machine; I think it has something to do with some of the other processes that the browser spawns.

As for gnome-music, I should've been more specific; the issue is actually with it causing the compositor/clutter/gnome-desktop thread to use way too much CPU, as though PyGTK is using way too many cycles when communicating with the desktop.

Unrelated gnome problem, though -- all of my keyboard shortcuts to launch applications (such as Ctrl+Alt+T) stopped working suddenly, and nothing in particular seems like it should've triggered that? This is all on an up-to-date, nonbroken arch+gnome config. I'd take a screenshot of htop reporting the same CPU usage except that gnome's screenshot tool seems to be included among the shortcuts that broke at some point in the past few days (makes sense, since it technically launches an application) ... I'm sorry I used lxtask and made you worry

Nevermind, application launching keyboard shortcuts are fixed after restarting gdm. Guess that must've been some weird race condition in setting up the display. So that just leaves my original problem of Gnome Music being very inefficient
