Comment 11 for bug 1024621

Just came again across this bug while testing https://code.launchpad.net/~mixxxdevelopers/mixxx/sample-grid , which uses the latest code from lp:mixxx/1.11. This is the first time i had the issue on MacOSX 10.8.2. It seems to me that the occurrence of the bugs depends on whether the current session had a sample deck playing or not , similar to lp:1013768

The GUI hangs for while the audio continues to play in the background. The GUI recovers after some time and the waveform is visible in the Decks.

To reproduce:
* Start Mixxx
* Load and Play a track in the Sample Deck
* Drag and drop a Track to Deck 1 or 2, one of them hangs

Instruments said, time is wasted in WaveformRenderPreroll during hang (see image)
