Embedded mpv crashes on Wayland due to EGL context failure (works on X11)

[erhardinho]

Environment

• OS: Pop!_OS (COSMIC / Wayland)
• GPU: Intel (Mesa)
• App version: MaxVideoPlayer 0.3.8 (installed .deb build)
• mpv version: 0.37.0 (system mpv works fine in CLI)

Problem

When launching the installed app normally on Wayland, the app crashes immediately when opening any channel/stream from the UI.

On X11, the application works correctly and video playback succeeds.

Logs

Wayland (crash)

[Linux renderer] Wayland EGL display via eglGetPlatformDisplayEXT
[Linux renderer] Wayland subsurface + wl_egl_window + EGL context created
[Linux renderer] render_frame: eglMakeCurrent failed
Segmentation fault (core dumped)

X11 (working)

[Linux renderer] X11 child window + EGL context created (OpenGL Core 3.2)
[Linux renderer] render_frame: eglMakeCurrent failed
[Linux renderer] render context attached
frame presented (#0, #1, #2...)

Expected behavior

Video should play normally under Wayland without crashing.

Actual behavior

• Wayland: Application crashes immediately when opening any stream/channel
• X11: Video plays correctly and renders frames successfully

Workaround

Running with X11 backend avoids crash:

GDK_BACKEND=x11 max-video-player

Notes

• mpv CLI works fine under Wayland
• Issue appears specific to embedded mpv renderer in tauri_plugin_mpv
