Description G. Náray 2010-01-15 22:00:27 UTC

Audacity CPU consumption rises steadily when it is not being used

Reproducible: Always

Steps to Reproduce:
If an Audacity window is left open and not being used (so it does not have focus) then it's CPU usage will slowly rise until (if left long enough) it uses all the available CPU.

Actual Results:  
Audacity uses all the available CPU after a while.

Expected Results:  
Audacity should not use all the available CPU when idling.

This is a bug described on webpage of Audacity. For more details, see:
http://wiki.audacityteam.org/wiki/Known_Issues
It is worth mentioning that the solution and patch for this problem is also found there. To be sure, here is the URL of patch (for wxGTK):

To clarify, the leakage occurs in wxGTK and affects other applications (including all wxPython ones), fixing it needs the patch applying to wxGTK-2.8.10.1 and and ebuild version bump. Audacity (all beta versions) should then start behaving itself.

So this is a wxGTK bug in the 2.8.10.1-r* ebuilds, not an Audacity one.

Patch to the ebuild for wxGTK 2.8.10.1 to apply the required fix

... and this is the patch to the ebuild so that the patch gets applied.
