trouble with trail renderer in unity 5.5.0f3

Hey there,

i decided to upgrade my unity, and am now having issues with my trail renderer, ive attached a screenshot.
as you can see, it is now twisting. this was not happening in my previous version (i think it was just unity 5.0.x or something like that).

i see there is a new setting "alignment" with options 'view' and 'local'. setting to local seemed to help a bit, but its vertex's still randomly tweak.

any input on this? how to fix it? when it will be fixed? its ugly lol

thanks
