Short description of error
Not sure if this is by design or a bug, but modifiers such as thickness, noise... are not aplied to final render when not in Object mode.
Exact steps for others to reproduce the error
1.) Create grease pencil object or use Suzzane, throw some noise/thickness and other visual modifier on it.
2.) Render while in Object mode and compare to other modes.
Looks like this should be set by display icons in the modifiers, but they do nothing even in viewport
