ShortPoint design elements are not rendering in Chrome
This issue affects both SharePoint on-premise and Microsoft 365 environments.

Solutions
SharePoint 2019 and Microsoft 365
Polyfilled package versions were created for the majority of active ShortPoint SPFx versions. The packages have been tested by the quality assurance team and the updates were deployed to ShortPoint customers.
As a result, if you are currently using a lower ShortPoint SPFx version, you simply need to upgrade to the latest version (8.3.4.599) to resolve the problem. To upgrade, click the [1] ShortPoint logo and select [2] Dashboard:
Click Upgrade:
To proceed with the rest of the steps, you may refer to this article in upgrading your version using ShortPoint SPFx Auto Upgrade Feature.
Important: Once you are done upgrading, but still the contents are not showing for your browsers, it is possible that the ShortPoint SPFx app from the App Catalog is outdated. To verify, please go to Site Contents and look for ShortPoint SPFx app.
Click the three dots, then click Details to verify the version you are using. If it is lower than, 7.1.5.38, then it means you need to go through the upgrade process.
Please follow this article to begin with upgrading your SPFx app: Tutorial: How to Switch to "New Upgrade" (if you are on a version below 7.0.x.x)
SharePoint 2013/2016
To mitigate this issue, you may use the solutions described below:
Go to the folder where ShortPoint is installed and open the shortpoint.master.js file. The folder location should look like this:
C:\Program Files\Common Files\SharePoint\Web Server Extensions\16\TEMPLATE\LAYOUTS\ShortPoint.Foundation\UI-Core\js\
Note: If you cannot find the shortpoint.master.js file there, try to replace \16\ with \15\.
Copy the code below:
!function(){if(window.mutationEventsPolyfillInstalled)return;window.mutationEventsPolyfillInstalled=!0;let e=new Set(["DOMCharacterDataModified","DOMNodeInserted","DOMNodeInsertedIntoDocument","DOMNodeRemoved","DOMNodeRemovedFromDocument","DOMSubtreeModified",]),t="Polyfilled",n={attrChange:0,bubbles:!0,cancelable:!1,newValue:"",prevValue:"",relatedNode:null};function o(e,o,a,r){let l=Object.assign({},n);a&&(l=Object.assign(l,a));let d=new Event(e+t,l);d.attrChange=l.attrChange,d.newValue=l.newValue,d.prevValue=l.prevValue,d.relatedNode=l.relatedNode,r&&Object.defineProperty(d,"target",{writable:!1,value:r}),o.dispatchEvent(d)}function a(e,t){let n=document.createTreeWalker(e,NodeFilter.SHOW_ALL);do t(n.currentNode);while(n.nextNode())}let r=new Map,l=new Set;function d(e){let t=[];for(let n of(e.forEach(function(e){let n=e.target,r=e.type;"attributes"===r?(null===e.oldValue||null===n.getAttribute(e.attributeName))&&o("DOMSubtreeModified",n,{attributeName:e.attributeName}):"characterData"===r?(o("DOMCharacterDataModified",n,{prevValue:e.oldValue,newValue:n.textContent}),t.push(n)):"childList"===r&&(e.removedNodes.forEach(e=>{t.push(n),o("DOMNodeRemoved",e),o("DOMNodeRemoved",n,void 0,e),a(e,e=>o("DOMNodeRemovedFromDocument",e,{bubbles:!1})),o("DOMNodeRemovedFromDocument",n,{bubbles:!1},e)}),e.addedNodes.forEach(e=>{t.push(n),o("DOMNodeInserted",e),a(e,e=>o("DOMNodeInsertedIntoDocument",e,{bubbles:!1}))}))}),t))o("DOMSubtreeModified",n)}function i(e){let t=e.getRootNode();for(;t instanceof ShadowRoot;)t=t.host.getRootNode();return t instanceof Document?t.documentElement:t}let u={subtree:!0,childList:!0,attributes:!0,attributeOldValue:!0,characterData:!0,characterDataOldValue:!0},s=Element.prototype.addEventListener;function c(n,o,a){return e.has(n)?{fullEventName:n+t,augmentedListener(e){Object.defineProperty(e,"type",{writable:!1,value:n}),o(e)}}:{fullEventName:n,augmentedListener:o}}Element.prototype.addEventListener=function(t,n,o){if(e.has(t)){!function e(t){if(l.has(t))return;l.add(t);let n=i(t);if(r.has(n)){r.get(n).count++;return}let o=new MutationObserver(d);r.set(n,{observer:o,count:1}),o.observe(n,u)}(this);let{augmentedListener:a,fullEventName:f}=c(...arguments);s.apply(this,[f,a,o]);return}s.apply(this,arguments)};let f=window.removeEventListener;Element.prototype.removeEventListener=function(t,n,o){if(e.has(t)){!function e(t){if(!l.has(t))return;l.delete(t);let n=i(t);if(r.has(n)&&0==--r.get(n).count){let o=r.get(n).observer;r.delete(n),o.disconnect()}}(this);let{augmentedListener:a,fullEventName:d}=c(...arguments);f.apply(this,[d,a,o]);return}f.apply(this,arguments)},console.log(`[SPX]: Mutation Events polyfill installed (native feature: ${"MutationEvent"in window?"supported":"not present"}).`)}();Paste it at the very top of the file:
And save the file.
The code re-adds the required APIs that were removed from the latest Chrome (127.0.x) version. This ensures that ShortPoint can load correctly on SharePoint tenants.
Note: A hard refresh of the page might be required to get the fix working. To perform this action, hit the Ctrl+Shift+R (on Windows) or Cmd+Shift+R (on macOS). This will reload the page with the latest files.
