Grease pencil object is refusing visual effects I'm new to blender 2.92 and I've a book with cool tutorial series with quick-start guides for blender 2.80, and I've learned many things so far! But a problem arises when I try to apply an effect to suzanne object:

The glow effect is ignored.
As shown above, nothing happens and I did everything I could for hours... I applied all properties in sidebar, but they are being ignored...
I know that the lessons are meant for 2.80, I keep up updated with latest online manual docs.
You need to be in Rendered view to see Grease Pencil effects.
