Quote from ZeksieYou have the range finder enabled, which is fading frames that are out of range for your defined spell. :)
I'll check but I'm not sure that's it because this happens on every single target, regardless of how far they are, even when i target myself. Also, my warlock doesn't use a spell defined. He uses the 30 yard setting and it still happened when I target myself(I always target myself when setting the frames up so I can see the target's/target target's/target's/target frames too).
I see what is doing it. When it brings the settings over from another character, X-Perl is still using the other character's spell to determine whether the frame should be dimmed or not, even tho the spell box correctly shows the current character's spell. I have to alt-click on the spell box to reset it's spell to the current character's spell(even tho it looks like nothing changes), for the target box to correct itself.
