Here are my sites . https://www.tom-abraham.com/ and https://www.sabrina-abraham.com/en/. In both site when loadind and when switching to different language background image flickers . I have enabled parallax effect and background attachment is set to fixed,background position is default, background repeat is no-repeat and background size is set to cover . I have built the site using elementor plugin and ocean wp theme . Can anyone help me fix this issue?
