**Summary**

Hit an issue where Nautilus froze every time I closed the window. To debug:

- Ran Nautilus from terminal with GDK_BACKEND=wayland to watch logs
- Tailed journalctl --user -f and dmesg -w — no OOM/segfaults, just a hang
- Verified that GDK_BACKEND=x11 closed cleanly → narrowed to Wayland path
- Tried GTK_USE_PORTAL=0 alone and it still froze
- Forced GSK_RENDERER=gl, it closed cleanly, but showed a deprecated warning
- Finally used GSK_RENDERER=ngl, works, closes fine

So it’s GTK4’s Vulkan renderer hanging on teardown (NVIDIA Quadro M1200 here, but likely all NVIDIA).

FYI I also confirmed the calculator hangs as well. 

**Steps to Reproduce**

1. Run Nautilus under Wayland:

```bash
GDK_BACKEND=wayland nautilus --no-desktop
```

2. Close the window
3. Observe freeze (no crash, just hang)

**Workaround**

Run the app with ngl renderer instead of Vulkan:

`GDK_BACKEND=wayland GTK_USE_PORTAL=0 GSK_RENDERER=ngl nautilus --no-desktop`

**Permanent local fixes**

a) App-specific (minimal):

Patch the desktop entry so Nautilus always runs with ngl:

```bash
# In case it doesn’t already exist
mkdir -p ~/.local/share/applications
cp /usr/share/applications/org.gnome.Nautilus.desktop ~/.local/share/applications/

# Then edit ~/.local/share/applications/org.gnome.Nautilus.desktop
# Change this line:
# Exec=nautilus --new-window %U

# To this:
Exec=env GSK_RENDERER=ngl nautilus --new-window %U
```

b) Global (affects all GTK4 apps):

Add to Hyprland envs:

```bash
# ~/.config/hypr/envs.conf
env = GSK_RENDERER,ngl
```
