fix(linux): detect NVIDIA GPU and work around EGL_BAD_ALLOC on Wayland#446
Conversation
Linux users with NVIDIA proprietary drivers on Wayland report crashes: "Could not create surfaceless EGL display: EGL_BAD_ALLOC. Aborting..." WebKitGTK's web process calls eglGetPlatformDisplay with the EGL_PLATFORM_SURFACELESS_MESA platform, which fails with NVIDIA's EGL implementation and triggers abort(). WEBKIT_DISABLE_DMABUF_RENDERER=1 (already set) only controls buffer sharing, not EGL initialization. Detect NVIDIA via /proc/driver/nvidia and: - Set __NV_DISABLE_EXPLICIT_SYNC=1 to prevent Wayland flickering - Force GDK_BACKEND=x11 on NVIDIA+Wayland (user can override) Also bumps version to 2.5.19.
