issue with --learn on hyprland

Bug Report: Failed to get EGL display on NVIDIA GPU (gesture learning mode only)

Description

Hexecute fails to create a Wayland window when using --learn mode, with error "Failed to create Wayland window:failed to get EGL display". However, gesture recognition works perfectly fine - gestures can be executed successfully.

Expected Behavior

Running hexecute --learn "command" should open an overlay window where users can draw gestures to train the recognizer.

Actual Behavior

The command fails immediately with:

2025/12/13 12:49:37 Failed to create Wayland window:failed to get EGL display

What Works

• Gesture recognition via hexecute (main mode)
• Launching hexecute through Hyprland keybindings
• Drawing and executing learned gestures

What Doesn't Work

• Learning new gestures with hexecute --learn
• The gesture drawing overlay window

System Information

• OS: Manjaro Linux
• Kernel: 6.12.61-1-MANJARO
• Compositor: Hyprland 0.52.2
• GPU: NVIDIA GeForce RTX 4090
• NVIDIA Driver: 580.105.08
• Hexecute Version: 0.2.0-1 (AUR package)
• Wayland Display: wayland-1
• XDG_RUNTIME_DIR: /run/user/1000

Environment Variables Tried

WAYLAND_DISPLAY=wayland-1
XDG_RUNTIME_DIR=/run/user/1000

EGL Libraries Available

$ ldconfig -p | grep -i egl
libwayland-egl.so.1 (libc6,x86-64) => /usr/lib/libwayland-egl.so.1
libEGL_nvidia.so.0 (libc6,x86-64) => /usr/lib/libEGL_nvidia.so.0
libEGL_mesa.so.0 (libc6,x86-64) => /usr/lib/libEGL_mesa.so.0
libEGL.so.1 (libc6,x86-64) => /usr/lib/libEGL.so.1

Reproduction Steps

1. Install hexecute on Manjaro with NVIDIA GPU and Hyprland
2. Run from terminal: hexecute --learn "kitty"
3. Error occurs immediately, no window appears

Attempted Solutions

• Running with explicit environment variables
• Launching via hyprctl dispatch exec
• Running from within Hyprland compositor context

All attempts result in the same EGL display error.

Additional Context

• Similar to Issue #11 but with NVIDIA GPU instead of Intel
• Related to Issue #17 regarding Wayland window creation
• Other Wayland applications (kitty, Hyprland itself) work fine with EGL
• eglinfo confirms EGL is configured correctly for the system

Possible Cause

The main hexecute mode (gesture recognition) successfully creates a Wayland window, but the --learn mode appears to initialize EGL differently or has different requirements that aren't met on NVIDIA systems.

Thank you so much for the detailed report! (If you used an issue template, could you point me towards it please?) As far as I know --learn doesn't do anything different with the EGL init side of things, so this is certainly an odd issue.

I'm currently a bit swamped with exams so I've experimentally and somewhat carelessly waved AI in the direction of this - and the result is https://github.com/ThatOtherAndrew/Hexecute/tree/fix-18.

Could you take a look and see if this fixes the issue for you please?
