Erm no... not with gliders.
I have been up to just below cloud base where tyou freezer your ... off because you're dressed for the 36+ C temperatures on the ground. And no glider I have been in has ever had loose fabric flapping in the wind.
Remember that this same fabric is not just on the fuselage, its on the trailing edge of the wings too.
Wings doing well over 160 km/h at some points.
There's no flapping. None.
