Steam client is a black window

[awsms]

I can see the cursor changing to "clickable stuff" when hovering on button locations, but the whole Steam window is black.
Using hyprland-git ( 0.51.0.r41.g766acad-1), on an NVIDIA (RTX 4070) GPU + AMD APU (AMD Ryzen 7 8845HS w/ Radeon 780M) laptop.

edit: Steam is using the NVIDIA gpu, can't make it use the AMD one.
