As said in the title, the playhead is not displayed anymore after several loops of the sequencer when messing with a sample start point in override playback mode in the waveform editor.
I can take a video if necessary but it is easy to reproduce I think.
Conditions are for example
-load an already existing beats with long loops (for example 4 bars long loop)
-go in the waveform editor
-press A to activate the playback override mode when the sequencer is running.
-mess with the start point with the select wheel
-after a few tweaks the playhead disappear or is not displayed anymore.
