This was working OK but now a vector image placed inside of another vector image is heavily pixelated. The problem seems unique to this file as it works OKed before and in other tests I've done.
The file is linked, not embedded. I've tried re-saving/ re-naming the original and replacing it. Both via the Replace option in the Resource Manager and actually deleting the graphic and replacing it. I've checked and tried different view modes (it is set on Vector).
It seems that Designer is showing a cached low-res preview version of the placed file and I cannot find a way to refresh it.
Any suggestions to force Designer to actually load the linked file?
