Short description of error
Hi, i i have bug on Grease Pencil contours. When i move camera in animation contours vibrate, changing size. This is not problem with my PC, because i tried it on another and problem is the same. I tried Anit-Aliasing, change render engine (Cyles and Evee), the same bug is in viewport and in render animation. I'm attach the video of this bug. This bug occurs just with camera or object move.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

  1. Create Grease Pencil object.
  2. Move camera to "zoom" it.

This a know issue with Antialiasing. There are already plans to fix it, but still it's in the ToDo lists.

@Clément Foucault (fclem) do you want merge this in any other task?

@Antonio Vazquez (antoniov) We had this issue with the UV drawing. We can try snapping the points to the nearest pixel to avoid this kind of shimmering. This would be much simpler than trying to have much better antialiasing.

But yes we can merge this to the other task.

Okay. So thank you for answers and i waiting for updates. Btw. when i turned off antialiasing i have the same problem. Is there any chance at the moment to make such a camera move?

@Kacper (kacszu77) I know that @Daniel Martinez Lara (pepeland) had the same issue and he solved render to double size and then scaling down, but he can comment you better how he solved the issue.
