Linux: Occassional temporary freezing after loading a song

I’ve been hesitant to report this because I can’t find much in the way of reproducibility but renoise 3.1 is freezing for about 5 seconds after I load a song, usually 10 seconds or so after I have started playing it. It doesn’t happen every time and I’ve experienced it with large/complex songs and empty songs. There is nothing in the log to suggest there is a problem.

So I suppose I am asking if there is a known issue with this? I didn’t get this with the release candidates, only since the 3.1 release.
