AppImage fails to initialize GL context on Wayland with Intel Haswell GPU

[rumnav]

The official Hiddify AppImage fails to start on systems running a Wayland session with Intel Haswell (4th Gen) integrated graphics, showing the following error:

** (hiddify:XXXX): WARNING **: Failed to initialize GLArea: No GL implementation is available
(hiddify:XXXX): Gdk-CRITICAL **: gdk_gl_context_make_current: assertion 'GDK_IS_GL_CONTEXT (context)' failed

Environment

• Desktop: KDE Plasma (Wayland session)
• Base OS: Ubuntu 24.04 (or derivative)
• GPU: Intel HD Graphics 4600 (Haswell, Gen7)
• Kernel driver: i915
• Mesa version: 25.0.7
• User is correctly added to video and render groups.

Verified working components

• OpenGL is functional (glxinfo reports OpenGL 4.6 via Mesa).
• EGL is operational (eglinfo shows valid configurations).
• A standalone GTK GLArea test application renders successfully under the same session (blue window appears).
• The issue is specific to the Hiddify AppImage — other OpenGL/GTK applications work as expected.

Additional notes

• The same AppImage previously worked, suggesting a regression after a system update (e.g., Mesa, GTK, or Plasma).
• Forcing software rendering (LIBGL_ALWAYS_SOFTWARE=1) does not resolve the issue.
• The AppImage does not accept GPU-related flags (e.g., --disable-gpu), as it uses a custom launcher.

Request
Please consider:

Rebuilding the AppImage on a recent Ubuntu 24.04 base with updated Flutter/GTK dependencies.
Improving fallback behavior for systems where hardware-accelerated GL context creation fails.
Providing an alternative distribution format (e.g., Flatpak) with better sandboxing and driver compatibility.

Thank you for your attention.
