Up to a point of course. The fluttering will lead to stretching and wear of the seams / stitching. This in turn can increase the bagginess of the leech and in so doing lessen the sails performance. But this is over a period of time and has to be strong vibration to occur.
Stretched sails are common anyway !

Hi try adjusting the tension on the kicker, and adjust the leech line a little at a time. There is a big difference between sloppy flapping on a beat,close hauled, and vibration of a well trimed sail, try adjusting the down haul line at the foot of the main,tensioning the luff of the sail. Adjusting the kicker tension increases /reduces the downward force of the boom, stretching the body of the sail causing the leech to flap/vibrate. Getting the above right produces a very pleasing "Vrooom" sound on a good beat, showing that the sail is working as well as possible . Hope that helps you

[I must mention however that this thin line running along the leech (don’t know the name) is broken ]

Trailing edge flutter is a real problem. While the reasons it occurs are correct you don't have to put up with it. The leach line will increse the tension on the leach to minimise flutter. One trick the sailmaker does is to put a concave curve in the leach. Unlike most mainsails with roach which is a very convex curve.(but they have battens to control the leach) The flutter problem will become worse as the sail ages and the leach stretches.
If the leach cord will not stop the flutter then it is time to take it to the sailmaker for adjustment of the seams at the leach. You could try to flatten the sail with mainsheet tension /vang tension but basically the middle of the sail is taking the load before you tension the leach. good lcuk olewill
