I've noticed this a long time ago; the play marker doesn't snap to the grid lines on the playlist perfectly.
It appears to be perfect but when you zoom in, you can see that the play marker and grid lines are off! IT BUGS ME OUT!
This same behavior carries over to clip fades when fading in/out clips from the edges... they snap to something but it's not the grid!
I just want SONAR to take care of all these little annoying nuances once and for all! It's almost 2017 and they're still there!!!
There's a "feel" - it's smooth, clean - when you work in other DAWs... and that's just from doing simple things!
I still love you, SONAR and it's creators but C'mon!
Rant over.
