Yep Qubes is brilliant. However they desperately need to start writing custom unikernels to improve the performance. Additionally there has GOT to be a way to sandbox the GPU. They need to find something better than all their CPU rendering shenanifans.
Yeah haha the performance is horrible, especially on electron apps or websites with heavy JavaScript. The CPU rendering is very nice for privacy, basically makes the Whonix qube unfingerprintable, but I'd love an option for other Qubes.
