Starcraft II full system crash with Esync/Fsync?

Hi all,

Been getting back into playing Starcraft II since it started working with d9vk awhile back. But I was experiencing full system lockup every time I played a session online. It took a lot of trial and error, but after disabling Esync all my crashes went away. I was wondering if anyone else has been experiencing this problem?

My system:
RX Vega 56
Ryzen 1700
Arch Linux w/ latest ACO mesa 19.3-git (I have ACO disabled for this title to rule that out)

I’m thinking since the game only uses 2 cores it doesn’t really need Esync anyway, I haven’t noticed any performance loss… But wonder if I’m just in the minority here.
