Progressbar color issue, strange acting

This is a screen of my progressbar. Well not always but sometimes it acting strange like this. I mean instead to be in one color it get confused like this on the picture. I do not do anything sp开发者_运维问答ecial I just update the progress...

Does anyone have this kind of experience with progressbars ?

I must mention that this progressbar has 3dip for layout_height property

I made factory data reset on the phone and that fix my problem

Well afrer setProgress(something); I also done invalidate(); so this thing helps avoiding this kind of wired problems
