Yes, used the default ./configure. Gtk version is 2.20.1.

The levels start off looking as they should, but appear to accumulate

until peaked out after a couple of seconds. This is when it gets

sluggish - switching tabs will take a second at minimum. Hitting the

reset peaks buttons resets the levels but they immediately peak again

(ie the accumulation stays). After stopping the audio playing (sox

play on command line) the peaks take a couple of seconds to drop, and

CPU usages falls back to relatively normal levels.

Negligible.
