It's likely due to nvidia driver currently does not fully support offloading with vulkan for native wayland apps. Driver 545.29.06 introduces such support but it's not full yet, some apps work, some don't. Try switching adapter to intel one, for me ppsspp works fine with it. Another workaround is to set SDL_VIDEODRIVER=x11 environment variable.

Nvidia supports Wayland+Vulkan just fine now, so it can't be driver issues (it works fine in many other cases on Wayland).

This isn't only with the Flatpak, as I'm using the package as provided from Arch's extra repo. It seems to be that SDL's default x11 video driver is the culprit; forcing PPSSPP to run with SDL_VIDEODRIVER=wayland fixes it on Wayland.

In fairness, this might be either an SDL or Wayland bug, as the opposite is true in trzy/Supermodel#121's case
