I’ve noticed that there are notifications now if a programme is taking too much ram and the kernel kills it.

Were they there before or it’s an update from the DE or notification manager.

I can’t tell where you’re getting this message from, but kernel logs would mention “OOMKill”, so I’m assuming this isn’t from the kernel itself, but another monitor logging it and reporting on it perhaps.
Create extra swap and that will help prevent this.
It was crashing while trying to render with vulkan so I’m guessing it’s vram. I do have 32GB ram so I don’t think it was using that much
