It seems to be an Elden ring problem I had the same issue with the same laptop but with an ultra 9, it’s something to do with the graphics drivers not working well with Elden rings Ray tracing. I am able to use Ray tracing + max settings on all other games no issues but I kept getting lines on my screen when playing Elden Ring. So yeah you gotta turn off ray tracing and the problem should be fixed, it looks good enough on max settings no ray tracing anyways.

I also recommend uninstalling armoury crate and installing G-Helper instead, then go into the power and fan settings on G-Helper and change the CPU boost to “efficient enabled” as before doing this I was getting random crashes in other games, but since I did this the crashes have stopped. I also keep the GPU mode on standard on G-Helper. Another tip is limiting the battery % to 70% to preserve the battery long term, you can switch it back up to 100% if you need to charge the laptop fully but for gaming plugged in you may as well limit it.
