You can try one of the previous driver versions:
1.Delete C:\AMD folder
3.Has your monitor FreeSync support? If yes, try to disable FreeSync in Radeon settings>Display
4.Also MSI Afterburner has compatibility issues with ReLive drivers. If you have it running in background-close it before start this game.
Was this something that appeared only when you updated to Crimson 17.2.1?
Additionally, does this only happen in Battlefront?
Can you post an image of what you see, as that would help convey the problem.
Im seeing anomaly in For Honor too..., I think that it is the 17.2.1. So, is it WHQL 17.2.1 or not ?
It is WHQL (which is dated 2.22.2017) but it means nothing in terms of stability and compatibility.
The best driver for you is that which cause you no problems.
You can try to clean install 17.2.1 Windows 10 (64-bit) by following my previous instruction.
