This is a pretty strange one. AE CC2017 OS X 10.12.3
So while rendering a comp, the render queue window will change the date and time of previously rendered comps. The render time will be changed to "0 seconds" and the Started time will update to the current date and time every few seconds.
Here's a video of that in action during a render:
While this doesn't exactly seem to do any harm aside from removing reference data of how long things took to render, I assume it can't help to have all that extra updating going on during a render. . .
Anybody else notice this?
Yes. This is a bug in 14.1.
