Blank screen upon launching, GNOME 46.1 (NVIDIA+X11)

[carterprince]

Describe the bug

Blank screen upon starting the app.

GPU is NVIDIA, DE is GNOME 46.1 on X11, installed via the Flatpak (from GNOME Software).

Error log:

~ $ flatpak run com.modrinth.ModrinthApp

Running with root privileges produces the same output.

Appimage downloaded from https://modrinth.com/app produces a similar error, but instead of a blank screen it just crashes:

~/Downloads $ chmod +x modrinth-app_0.7.1_amd64.AppImage && RUST_BACKTRACE=full ./modrinth-app_0.7.1_amd64.AppImage

Tried to install from the AUR (modrinth-app-git), but it produces a seemingly unrelated error about yarn and pnpm.

Steps to reproduce

1. Install the app on GNOME 46.1 (NVIDIA+X11), AppImage or Flatpak.
2. Try to launch the app.

Expected behavior

App displaying some UI

System information

OS: Arch Linux (6.8.9-arch1-2)
DE: GNOME 46.1 (X11 display server)
App Version: v0.7.1 (from Flathub)
GPU: RTX 3070 Ti, Proprietary NVIDIA Driver (nvidia-550.78-2)

Additional context

No response

[carterprince]

Running with WEBKIT_DISABLE_DMABUF_RENDERER=1 or __NV_PRIME_RENDER_OFFLOAD=1 fixes the Flatpak, but the AppImage still crashes.

So running

flatpak override --user --env=__NV_PRIME_RENDER_OFFLOAD=1 com.modrinth.ModrinthApp

will make the variable permanent.
