Hey man !!! You will never believe what was causing that white stripes ?!
THE "Sticky Notes" more persistently the vertical "scrolling bars" of my two sticky notes! like when I was changing a theme while "Sticky Notes" were minimized, you could see that white stripes, I just needed to maximize them and minimize again in order to get rid of them. But it was only happening with new installed themes! so if I change between themes, which were installed some time ago the stripes were not appearing. plus it's happening only when my sticky notes are in the right side of my screen. Maaaaaaaaaaaaaaan! this is so stupid
and BTW I never liked Sticky Notes! they are so incomplete. they could have been more flexible!!!
But another thing is that I had Sticky Notes before also, but I never had this white stripes...
so what do you think is the reason???
check the screen-shot out!!!
