clipping of custom icons

[RedYggdrasil]

Hello ! I have a problem when I try to use custom icons, they appear and disappear in fade nearly every few frames.
My code :
fullscreenEnterIcon = {function(){return(<Image resizeMode="contain" source={require('wada7Resources/playerVideo/FullScreenIcon.png')} style={{height : 30,width : 30}} />)}}
