I see, well hopefully it'll get merged in the various compositors soon then! Wayland was a non-starter for me with that issue, and is precisely what led me to AMD.
I haven't kept up with the explicit sync support since I eventually did migrate over to AMD in October after the 545 Nvidia driver came out and didn't impress me at all - however I did hear in passing that you can get the explicit sync patch already in some ways, just a quick search reveals that Arch has this in the AUR already as xorg-xwayland-explicit-sync-git and that Nobara might already have it (I can't find official confirmation on this).
So your mileage may vary and it might require a varying level of work depending on what distro you run, however it might be worth looking into a bit more.
It's effectively install distrobox, save the config, run distrobox assemble and then distrobox enter rocm and clone the Automatic1111 stable diffusion webui somewhere and run bash webui.sh to launch it.
Does your BIOS have "Enable Resizable Bar" and "Above 4G Decoding" options? Both of those were off on mine, and I had the same problem until I flipped those on.
500 down and 40 up through Spectrum (east coast of the US). I'm always quite surprised with how well WiFi 6 works, I can pull down the full 500 from my Steam Deck and PC - ironically the network transfer is implemented badly as I'll get about 100 down over the local network so it's faster to download over the Internet.
There is also a flag to list which I always forget and lookup each time
That would be -t, which I tend to remember as "test", as in testing to see what is inside the archive!
tealdeer is a great program to have installed for easily getting a breakdown of the flags of pretty much any CLI app that at least I can ever think of!
For what its worth, while its not viewable on the Flathub website anymore, it can still (at the time of my writing) still be downloaded/installed through the flatpak command.
I was able to start a stream session and it did come up, although it kept reporting connectivity quality issues and it seemed like it was streaming at really low-bandwidth.
However, I normally stream via Sunshine/Moonlight and haven't tried the native Steam version in a while since it normally doesn't work well for me, so I think that's something on my end rather than it being a bug (and the fact that it displayed the game to me indicates its no longer this bug, since it initialized and was at regular brightness).
Endeavour on my desktop, and Fedora Silverblue on my MacBook - good combination!
