On 5.6 trails are not only flicker, but also produce connected lines to the origin of the object on macOS (OpenGL) and Windows (DirectX 11) (but not on iOS with Metal).

I am seeing this in 5.6 beta. Not only does the trail flicker now, but it draws odd lines, like back to the trail origin.

We are experiencing this issue atm, after updating to 5.3.4. So this issue definitely do not seem to be fixed. Can it be reopened?

This issue started for me in 5.3.3, may need to go back to a previous version because of how crucial this is.

Definitely not fixed in 5.3.3
I'm using 5.3.3p1 and my trail renderers still flicker, completely shut off, etc.

Having the same problem, I'm using a pooled objects, each with Trail Renderer on, and when there are many of these the flickering starts to happen.
This almost exclusively happen when the array expands, thus new Trail Renderers are instantiated along with the objects.
I can't tell for sure, but from looking at it for a while, it looked as if trails were reading from other trails' memories.
Also, it may be that the trail completely disappears when two adjacent trail points are too far. Which, wouldn't be too surprising given the trails are reading from multiple buffers.
I can provide my scene for further examination if needed.
