With some testing I found a solution that makes browsing better. Set the ram to fixed without ballooning, and use mullvad browser (disable hardware acceleration). Fixed all performance issues, now yt 1080p and other streaming services works just fine. Not sure what mullvad does different but it works so not complaining, its a great browser either way. Other apps works fine, still not the best performance but that is most likely the screen res being pretty high. Tbh qubes works great now for daily driving.
Funny thing is that mullvad is the only browser that works fine, other browsers still laggy unless running on my archlinux qube. Browsers tested: firefox, chromium, brave, opera and mullvad.
