Video issues with Alan Wake 2 using Heroic

I'm playing Alan Wake 2 through Heroic and have noticed occasionally picture breaks during video (a white line across the image) as well as video smoothness degrades over time. By that I mean the FPS gets really bad. If I change the resolution it fixes it for a time, but then degrades again and need to switch the resolution again.

I'm running Bazzite with an nVidia RTX 5060 8GB OC and am wondering if it's a Bazzite issue or an nVidia issue. If I switch to an AMD RT 9060 XT 8GB (can't afford the 16GB) would that help? I'd prefer not to have to swap GPU's if I can help it, especially if there's no guarantee it will fix the problem. This is the only game I've had an issue like this with. Thanks.
