Gamescope Steam Magnifier with filtering enabled clipping

[xx404]

The Steam Magnifier works well so long as no filtering options such as Pixel, FSR or NIS in Steam (Gamescope) are enabled. Enabling any of these results in the screen being clipped when zoomed in and it's not possible to pan around the whole screen. Changing the game's video settings to fullscreen or windowed makes no difference.

Hardware: Legion Go
OS: CachyOS with gamescope version 3.15.13.plus1 (gcc 14.2.1)
