Logic Pro X Stereo output fader moving erractically


New Member
This is weird. At the end of my project, about last 2 bars the sound breaks up and the fader moves up and erractically. I have automation in project but seems to work ok. Also my CPU is spiking and audio indicates audio even when no audio us playing. Could it be a bug in software? Any guidance will gratefully receive. Apple MacBook pro 15 " 2015 model.
