Exact steps for others to reproduce the error

I figured out grease pencil starts to disappear when moving bone "Spine.001" (the root of all armature)
(but also disappears for some reason if moving other bones)

Windows and Mac OS behaves much differently.
What happens on Mac OS (in terms of rendering) won't happen on windows and vice versa.
But yes -- thanks for testing!

Seems to be fine in 2.83, but it's broken with 2.82a.

@linosia could you test that with the latest build --> https://builder.blender.org/download/
