Wave Editor window in Multi Mode Loop/Slice makes the sequencer lag

Probably already reported but just in case

I have a 15 second stereo 26k sample I want to slice in 8 pieces. I have kick, snare and hihat looping in the background.

When adjusting start and end points, switching from pad to pad with the A button or just with the pads makes the sequencer lags or sounds cut. Hard to describe but it is very audible.

Workaround for a smoother experience is using fader and knobs in main screen but it lacks a bit of precision when slices are very short.
