Getting ?debug=true in all js requests in pg load in 6.3

Hi all,

We are getting ?debug=true in all js requests in every page load in AEM 6.3. This is really debilitating our environments and page load is very very slow. Is there any setting which has to be done to turn this off? Even our custom scripts are getting loaded in the same way. PFB screenshots (didn't include the load of our custom scripts in these images due to privacy). Is there any quick resolution for this?
