Commit https://github.com/odoo/odoo/commit/cf5b3e1db5d312133eb1af7ff0d5471db47987e5 fixed a problem by creating another one: the parallax with a given speed appeared broken on page load (which is even more visible in 13.0 with lazy loading). This commit restores the design and solves the original problem. closes odoo/odoo#41594 X-original-commit: a9aa72ecb5350cc0e9fa5b6a17d4db8d2f1895fd Signed-off-by: Quentin Smetz (qsm) <qsm@odoo.com>
