Hey everyone.

Recently I tried installing bootcamp drivers on my iMac 2017 with Radeon Pro 560. Long story short, none of the 2020 drivers worked due to flickering or dual screen bug, which many of you are aware of.

TLDR: I found a strange solution that worked for me. I was able to fix the issue by changing the refresh rate to 59hz on my iMac and then back to 60hz.Drivers seem to work stable for now and I am just sharing this as it might help others.

Hey deltasierra and everyone else !

I'm having the dual screen bug (or when switched to single display, extremely wide and flattened display resolution) whenever trying to install any drivers from the March release or any newer (20.2 or newer).

Everything goes extremely well until the final few seconds of the driver installation, where half of the screen gets busted or I end up with dual screen bug.
It seems like such an easy fix somewhere in config or to resolve what the drivers think our actual active resolution is.

Delta, are you able to confirm the 59hz to 60hz worked? As in the dual screen merged back into one and the display settings on both AMD Adrenaline and windows show the correct reso?

Thanks so much!

PS All of this is for successfully running Hyper Scape which requires 20.2.1 or newer AMD drivers.
