Hello everyone,<div><br></div><div>I have been running into an issue over the past couple of months with Ardour and Ubuntu.</div><div>When using Ardour intensively in Ubuntu for a couple of hours (switching between songs, doing recordings and mixing, etc), Ubuntu slows down dramatically. By Ubuntu I assume the couple Unity/Compiz - Alt+Tab takes seconds to appear and react to commands, the Ubuntu Dash becomes horribly slow and the only thing I can do is reboot the machine. In the mean time, Ardour and other software are still running pretty much ok. Checking the processes, Compiz and X are the ones using the processor a lot.</div>

<div><br></div><div>This doesn&#39;t seem to happen with any other software but Ardour (I&#39;m using Hydrogen or SuperCollider a lot), and I did a few tests with Gnome3, there it seems to be ok.</div><div><br></div><div>

My setup is as follows:</div><div>- Ardour3 Beta5</div><div>- Ubuntu 12.10 64bit</div><div>- Using the Radeon open driver (FGLRX creates a lot of xruns)</div><div><br></div><div>Now, I am not trying to start a conversation &quot;Should I use Compiz when playing music&quot; or &quot;Ubuntu is crap, what else should I use?&quot; :)</div>
<div>I like Ubuntu, I like Unity and I like Ardour3!</div><div><br></div><div>I am just checking if other people are experiencing the same issue, if there is a solution to this problem, what additional testing I should do or  what additional information I should provide.</div>
<div><br></div><div>Finally, if it is a bug, where should it be reported? Is this an Ardour bug as it seems only Ardour is making this problem happen, or is it an Ubuntu/Unity bug as it is the application actually slowing down?</div>
<div><br></div><div>Thanks in advance for the help!</div><div><br></div><div>Aurélien</div>
