This isn’t really driver related. It is the Wayland compositor’s job to properly handle multiple GPUs, which is lacking in some (a very popular, Wayland library that lacks proper multi-GPU support is wlroots) compositors. Vulkan drivers and DRM are already enough to properly handle multiple GPUs. I guess Wayland implementers just haven’t cared enough about the issue, or maybe are figuring out a “perfect” way to address it (a la 3 year long pull request on wayland-protocols repo incoming)
From the repo:
Technically, even if your data is encrypted, the amount of data you send (and the time between packets) can be analyzed to at the very least figure out what website you’re on, and who knows what else (i.e. Youtube’s HTML, CSS, and JS files will be different than Facebook’s, so the amount of data sent will be different, and you can train an AI to recognize these patterns). This app pretty much it protects you against packet analysis from your ISP or anyone else who could monitor your network. I guess this assumes that you’re using a VPN or some sort of proxy since it’s not very useful otherwise.
