Transparent layer produces incorrect draw

[David_Sinton]

We have a map that when exported to jpeg, one of layers doesn't get represented correctly. The symbology for that feature creates a strip the length of the map. In the screenshot below the simple hatch symbology runs erroneously across the map. This only happens when the symbology is hatch symbology or when the transparent mask (eastern portion of map) is turned on. This is ArcMap 10.4.1. Does anyone have an idea how to get rid of this?

Thanks in advance,

David

Solution found: decrease dpi by 1.

That is really weird. Does this behavior happen every time at that particular DPI? And would increasing it by 1 also fix the problem? I'm just curious.

Once it started it wouldn't stop at 350 dpi. It only happens when we use hatch symbology and have a mask with transparency. Then 349 worked. Increasing it to 351 also worked. I agree that it's weird.
