Windowing broken + fullscreen artifacts on Wayland since 1.1.82.200
Hey folks,

Thanks for putting in all this effort to make Steam Link work on Linux platforms, especially with Wayland DEs/compositors.

I've found that since 1.1.82.200, the release that enabled/fixed hardware acceleration on my setup, I've been unable to get the Steam Link application (ran in Flatpak) to be windowed once the streaming begun, and since I have a 2K display on my client and an FHD one on the host, being in fullscreen means the entire content is stretched. Attempting to window the stream just results in it being rendered on the "side" of the display in the original resolution, the rest of the output just being black. Another curious issue I've found is that the stream no longer begins/starts being rendered on the display of that the splash screen / menu was initially started on, but rather always appears on display 0 -- in my case, this is a closed laptop screen, so for a while, I thought Steam Link was completely broken and was no longer rendering streamed content.

Here's some log output that might assist you, I tried windowing the content, you can see that by the texture resolution changes at the end:

+1 to this. I've been tinkering with Remote Play today and have ran into a brick wall because of this issue.
