in preferences -> user -> editing there are the playhead-shadow options. i guess they are
there since 12.5. i can't renember exactly since which version it didn't work for me anymore,
but in DR 14.3 and DR15b6 it doesn't.
there is no SHADOW-PLAYHEAD at all, it doesn't matter how many frames i put into that settings-box...
does this work for anyone?
it was incredibly useful for mastering having visually indicated which frame i watch exactly!
