Same here. Trails flicker when a new trail component is added to scene.

Having this issue as well, Unity 5.3.1f1.
I'd really like to see this fixed. I launch several objects with render trails in my project. Every time a new object launches, the trails of all the previously launched objects disappear for a split second before reappearing. This is fairly disruptive for my work.

Good thing I'm not the only one experiencing this, I thought I was going crazy. I hope they fix this soon.

Same issue here. I thought it might be my fault at first, so I spent a bit of time reproducing and tinkering with it.
I use trails on projectiles, and you fire quite a lot of them. I noticed that trails tend to flicker when a different trail is disabled. If I fire a single projectile, wait a bit, fire another, then the projectile currently in flight will lose its trail on the same frame that the projectile I fired earlier is disabled.
It could be coincidence, or it could be that Unity simply clears the wrong trail in the list when attempting to remove a disabled trail.

Similar issue in my game, i render trails that fly toward the camera (which is also moving forward), at the start of the scene the trails flicker on and off but seem to settle and render properly after a few seconds. The trails were fine on 5.2.3 but started flickering on upgrade to 5.3.0f4.
