Game Freezing issues with UltraWide but not regular monitor / Steamlink

I've got a dual monitor setup one Samsung C49RG9x 32x9 120hz Ultrawide and an old dell 1920 x 1200 60hz monitor. I'm using a Ryzen 7 5700x RTX 4070 and 32GB RAM, and have had freezing and hard crashing (reboot required ) issues since 0.3 that increased with the latest patch (also tends to crash more when using Vulken.)

I've noticed however that it only seems to crash when i'm playing with my Ultrawide, if I use the Dell Monitor, or steamlink to ipad (which also displays on the dell monitor) it never freezes. I'm guessing it just has more overhead with the lower rez to not trigger the issue, but just found it interesting and figured maybe it would help narrow down the actual cause for this specific crash.
