Well, i found out what is causing the problem, but i really can't solve it...
It's not interface related, cause, i checked out already with CTRL+\ and there is nothing in that area (when i move them around and nothing is there, those 8 shadow are still there)
Instead, i got my sleeves up yesterday, and reset my graphics to default and worked my way around up top... and found out that.... when i activate:
Post Processing Effects
It pops up... when i deactivate it, it goes away... i tried removing other effects when post processing are enabled without change, so obviously, post-processing effects are the cause... but i wonder, what's doing this!
I also posted screenshots on LOTRO forums in the video section, but here is the screenshot showing the result with post processing effects on and off...
Post Processing Effects = Off
Post Processing Effects = On
