Thunderbolt Display Flicker

Hi Everyone,

I like many others experiencing Flickering on my thunderbolt display since installing EI Capitan. So my question is this, Has anyone reverted back to an older OS to rectify the problem and did it work?. I am considering re-loading OS X Mavericks to see whether the Flickering continues and if it doesn't all well and good but if it continues to Flicker then almost certainly it's a hardware problem. Either way i feel there is nothing to lose anyway!. Your thoughts please.
