Decal Issue: streaks appear on some decals

Greetings!

I'm having a bit of an issue with decals in SolidWorks.  At some point, perhaps after an update, some of the decals on an assembly were altered.  A few decals began to show signs of streaking/fading that extended beyond the decal while other decals had no change.  The problem persisted when applied to a single part, see image below.

I checked to make sure that each of the decals shown had the same settings.  I've also tried deleting the decal from the library and reloading it.  It seems to be happening to at least a third of my decals in the library.

Any suggestions for a solution would be appreciated.

Regards,

Matt
