Audacity Forum

Running Fedora rawhide, audacity-1.3.7-0.6.beta.fc11.x86_64 appears to consume lots of CPU even when the application is "idle" or minimized.

If I run the following in a terminal window:

audacity & sleep 60; ps agx | grep audacity; sleep 60; ps agx | grep audacity

and if I immediately minimize the audacity window when it appears, I get the following output:

[[email protected] ~]$ audacity & sleep 60; ps agx | grep audacity; sleep 60; ps agx | grep audacity
[2] 13356
13356 pts/1 Sl 0:02 audacity
13356 pts/1 Sl 0:05 audacity

So, its consumed 3 seconds just minimized for 60 seconds.

I get the following if I run strace on it:

Process 13356 detached

Seems like it is much too busy.....

[If I leave the process "just minimized", it continues to eat CPU.

Here it is after about 3 more minutes:

13356 pts/1 Sl 0:33 audacity
13676 pts/1 R+ 0:00 ps agx

I've filed a Fedora bugzilla here: https://bugzilla.redhat.com/show_bug.cgi?id=494425

All suggestions/help welcomed!
