System:
Arch Linux
KDE Plasma 6.6.5 / KWin 6.6.5
Session: Wayland
Steam package: 1.0.0.85-7
GPU driver: NVIDIA 610.43.02

Setup:
Three monitors. Steam Link works correctly when all displays are 100% scale.
When one TV/display is set to 1.35 fractional scale, Steam Link/Remote Play becomes misaligned.
Changing only the game/main monitor resolution did not fix it.
Changing the TV scale back to 100% fixed it without switching to X11.

Expected:
Steam Link capture and input remain aligned regardless of fractional scale on another monitor.

Actual:
Remote stream/input/capture is misaligned when one monitor uses 1.35 scale.

Relevant log:
Steam streaming_log.txt showed changing capture resolutions and previously warned:
"Desktop capture unavailable, try running Steam with -pipewire"
