Currently when vector printing a view with non-solid fill patterns the patterns will always override objects (walls, equipment etc.) in the outcome, despite disabled masking options and color scheme location set to background. Solid fills are not behaving in the same way. This also applies to double fill patterns, as the solid fill will move behind objects, while non-solid will go to the foreground, despite of settings. Raster printing is giving the expected result.
There should be and option to keep non-solid Filled Regions in the background in vector printing as well.
