# Requires: chromium-changes.patch applied + rebuilt.

# --disable-gl-extensions reproduces the GPU-cap profile of ANGLE-D3D11
# (Windows) / GL-ES2 drivers, where the dst-copy fallback path is taken.
# It does not bypass any security check; it selects an existing code path
# that runs on real shipping configurations.
