A set of merge requests were opened that would effectively drop X.Org (X11) session support for the GNOME desktop and once that code is removed making it a Wayland-only desktop environment.
Going along with Fedora 40 looking to disable the GNOME X11 session support (and also making KDE Plasma 6 Wayland-only for Fedora), upstream GNOME is evaluating the prospect of disabling and then removing their X11 session support.
Some concerns were raised already how this could impact downstream desktops like Budgie and Pantheon that haven't yet fully transitioned over to Wayland. In any event we'll see where the discussions lead but it's sure looking like 2024 will be the year that GNOME goes Wayland-only.
AFAIK wine requires no special hardware support. It isn’t virtualizing anything, it just translates directx calls into OpenGL/Vulkan calls executed by your normal driver. If wine doesn’t work I suspect it’s something else
Have you enabled virtualisation support in your BIOS/UEFI? Many vendors ship their hardware with this switched off by default (and some hardware actually doesn't support it at all).
I don't have any issues with Xwayland and simultaneous key presses. Tested with Bottles (i. e. WINE), BeamNG (native Linux build) and the games from SCS Software (also Linux-native). I am running Fedora 38 Silverblue with an AMD RX 5500 XT GPU.
