Vertical Scroll Bar Flickering

[Prakash19921206]

Hi
in winform, i added metroTabControl, in metroTabPage i made AutoScroll : true. in metroTabPage i added a tableLayoutPanel (Dock: Top) i increased the tableLayoutPanel's height way higher than metroTabpage.
now when i run the app, i see vertical scroll bar, as i slowly move this scroll bar it flickers up & down a lot.
how to fix this?

Thanks
