Shadow Unit Frames - Large Glowing Box?
 

I seem to have some kind of error with SUF that I do not know how to fix.. basically it looks like the sprite for a glowing highlight is scaled HUGE. Any ideas what this could be. I tried doing a few things but no luck. It seemed to fix on /reload ... . Next time I'll take a screenshot.

Have you looked to see if it is a buff/debuff?

I think I found it is disabled the "priority" debuff highlight... fixed it.. but it would be cool to have a fix that allowed me to have that turned on.

Wouldn't you be better off posting this in the actual addon's comments where the author is much more likely to see it?
