Drop Shadow, Outer Glow, Etc. renders incorrectly on large polygons angled lines only.
When I make a drop shadow, outer glow etc. there are places on the shadow that end abruptly in intervals. I make a triangle or any polygon (even a rectangle that is rotated). Go to Effect>Illustrtator Effect>Stylize>Drop Shadow. Multiply:75%:0":0":0.5". Color Black. I've tried other colors and other settings for Blur and Mode. This does the exact same thing using Outer Glow. I have a 66" x 36" artboard on the examples below.

It's still doing it in 24.1.2

After some experimenting I determined that changing the opacity percentage had no affect on the shadow's error. Changing the blur, however, does. Here is the difference between a .5" blur and a 1" blur. And yes, these errors do print. They're not just on the screen.
