Judging from the color and shape that image might be related the te custom theme you are using.
Anyway I have never seen such an image in ROM's before so it might be part of some custom tweeks. So disabling them could solf you problem after a few tries.
BTW which Build are you using?
There's no real reason to use a different gwes though, is there? If you're doing it for the bold font fix, there's a much better fix for that.
