It's got to be an edge case for Wayland to be used with a 2GB VRAM card? Targeting recent cards and letting people using older hardware install x-windows, or whatever, seems sensible.

You say (in your blog post) "Linux" didn't work well so you reverted to "Windows", but as is so often the case you buried the distro/version info. You don't seem to have been using Win11 (later you mention Win7 & Win10Pro) ... So it's cutting edge software didn't work on my 2014 system, but older software did. The Linux/Windows aspects aren't particularly relevant AFAICT.

Nvidia refused for many years to properly support Linux, whilst AMD have supported it. So no surprise if a Nvidia card didn't work well/stably but an AMD one did.
