I do browser-based screensharing (of both individual windows and the whole screen), I have a mixed DPI monitor setup, I've played games on Steam, &c. I need no workarounds. GNOME just works.
About the only things I don't use are nvidia's crappy drivers.
Hope it works out for you.
GamingOnLinux stats — AMD GPU 40% and raising.

Anyone who wants stable, performant GPU today can buy AMD. Future is here. That's Wayland target.
I live in the past — Intel GPU, X.Org, xmonad. I've thought to wait a few more years but I've checked Sway, it works. I'll check waymonad, maybe it works, maybe I'll make it work.
Wayland GNOME and KDE works with NVIDIA.
1. Gaming. Just about nobody games on Linux with nVidia. Most people I know who game (from Linux) with nVidia GPUs use PCI passthrough to a guest VM running Windows. Very few use nVidia GPUs on their host system. My primary setup is a 2950x/128GB DDR4/Vega 56/2080 Super -- the latter goes to kvm exclusively.
2. "Research" such as machine learning. You don't need Wayland or X11 for this, and the proprietary drivers work the best. To be honest, this is a space where Ubuntu Server performs best. I keep one of these around in a VM (see above) for this purpose. (Mining also goes in this category)
Everything else can probably be done with an Intel or AMD GPU tbh.
I guess I'm the oddball here. 95% of my gaming is native Steam Linux apps on my Kubuntu box with a GTX1060 6GB.
