Fixed background image flickers when scrolling in internet explorer

Here is my site https://www.tom-abraham.com . The website is built using wordpress and elementor page builder plugin. The website works well in firefox,chrome browser . However the background images in about me section flickers when using internet explorer . I am using the latest internet explorer.I have set background-attachment fixed for the background image and also enabled a parallax effect . I know that background attachment fixed is causing this problem , but i want to keep the background fixed and also keep the parllax effect . How can i fix this problem ?

What about background-size:cover;?
