I'm having a hard time getting the map frame to keep its background color once added to a layout. I've got a nice gray color in the Map tab:
On the layout tab, however, it's plain white, even if I change the background color of the data frame separately:
Is this the intended functionality of these settings? There are no polygons or anything on my map covering the "background" - and as shown above, it's looking fine on the map tab. I'm wondering if there's just another setting somewhere that I'm not thinking of.
Forgot to share - if anyone is impacted, you can track this bug: BUG-000143484 https://support.esri.com/en/bugs/nimbus/QlVHLTAwMDE0MzQ4NA==. The improper functionality is the result of using blend modes in your layers. It has not been fixed in 3.0 as I hoped, but hopefully soon. When using a graphic rectangle as a workaround, be sure to set its labeling weight to none to avoid labeling problems. I label it with the bug number so I don't come back years later and wonder why the heck I did it this way.
didn't find it in the pdf
