+    # MeshLab renders through Qt's xcb platform, which creates a GLX context,
+    # and calls glewInit() against it. The default EGL-enabled glew is built
+    # EGL-only (no GLX dispatch table), so glewInit can't read GL_VERSION and
+    # the app fails to launch with "GLEW initialization failed: Missing GL
+    # version". See https://github.com/NixOS/nixpkgs/issues/531470
