X isn't 'deprecated' and pretty much everyone knows that Wayland is not a full replacement yet. Anything that is 3D accelerated (like games) just does not work with Wayland. Also, taking this tone when reporting an issue is just lame and really boring.
The poster edited their message and also apologised. I came because of this same issue in the hope of seeing an update.
Re Wayland, only nvidia users suffer from gbm, and it has been worked in now on maintained desktops. X has been supplanted for the majority of users for some time, and I have few issues even running dxvk on nvidia. Users with old devices are in trouble, but that is an issue with nvidia, not Wayland.
