So I've reverted to the stable version of mesa provided by Manjaro. Factorio indeed no longer flickers. The command below got me what I needed.

Thanks for the reply, no i'm running Manjaro actually. I installed mesa 20.3 through the software center. I think I might need to do some digging around to figure out how to use the older (stable) driver. I'll try to get Mesa 20.2

I just registered here to post that I'm having the same exact issue. I'm running the same version of mesa drivers. I have very little knowledge with linux and how to change drivers. If there is a workaround for this issue it would be greatly appreciated.
