Strange icon problem after Winterboard use

Hi ppl.

I've installed Winterboard and the theme ios' 86. I didn't like it, so I remove it and also removed the Winterboard.

However, the recents, keyboard and voicemail icons are strange, in low definition (just like the ios' 86 theme) - as you can see in the attachment.

Any ideia on how can I restore this icons to default?

Thanks
