Great experience with Wayland on Nvidia with GNOME 44
I mostly use AMD and have been using Wayland since GNOME 40 without any problems, loving the consistently perfect frames and fantastic scaling (with Wayland programs, but nowadays I use nearly no X11-only programs).
I tried Nvidia with Wayland a few times and it always was a clusterfuck. I remember when Nvidia just released GBM support on their drivers I actually compiled my own Mutter to try Wayland because there was a bug with the hardware cursor that overflowed the GPU memory. I even tried eglstreams a few times with the Nvidia-developed GNOME backend. No matter what, I always had problems with invisible programs, programs leaving trails like the cards falling in Windows 98 Solitaire when moving the window, slow programs, blurry programs, unresponsive programs, etc.
Today I tried again Nvidia with GNOME 43/Wayland on Debian 12 and also experienced lots of the same issues as I always had. I then moved to Sid with GNOME 44 and was pleasantly surprised to see nearly all my issues just go away. Have not seen any invisible programs, nor any trails behind windows when moved. I have seen abnormally slow programs though, the GNOME terminal seems to struggle when scrolling fullscreen, whereas my laptop with and AMD APU works perfectly.
Currently happily using GNOME 44 with Wayland on Nvidia, never thought I would get to say this. I'm hyped for GNOME 45 to drop in Sid!
Unfortunately, Wayland works terribly on my Nvidia MX150 GPU. It's an Optimus based GPU, so both the iGPU and the Nvidia GPU are running all the time. I've had my Nvidia GPU disabled for better battery life for a while now.
I went for an AMD APU on my laptop explicitly because I wanted to avoid hybrid graphics. While I would like a faster igp, for battery life and ease of use, APUs are fantastic.
