Resolution
For the "Rendering mode was changed to 'Grid Rendering' due to the Isolation Profile's 'Vector Rendering Settings'.
null" error, please implement the below, in the Isolation Profile referenced in the linked policy, to resolve the error.
From the above snippet, the boxes for the Grid Rendering URLs are unchecked. This ensures that the isolation engine does not attempt to change the rendering mode from the Vector Rendering to Grid Rendering. This actually would resolve the "Rendering mode was changed to 'Grid Rendering' due to the Isolation Profile's 'Vector Rendering Settings'. null"
Additionally, we recommend to select the JPG compression, instead of the PNG compression, with the image quality as shown in the snippet below.
Also, having checked the referenced policy for the request, we see that the Document Isolation Policy was used. See the snippet below.
Note
The Document Isolation Service (DIS) is used to render Office and PDF files remotely. It also support printing and download (controlled via policy).
The following file types are supported:
Word documents (doc, docx, dotx, dot, dotm extensions)
Excel documents (xls, xlsx, xlsm, xlm, xlsb extensions)
PowerPoint documents (ppt, pptx, pps, ppsx, potx, pot, pptm, potm, ppsm extensions)
RTF, CSV, TAB, TXT.
We recommend to not us Document Isolation Rule for regular web access. This can create instability. We recommend to use a custom rule to Isolate this URL, and have the rule placed ahead of all other rules. Typical setup of the rule may be as shown in the sample below, set up to allow access to Ofice365. See the snippets below.
Note: Ensure that from the Proxy, the URL is NOT Bypassed, If you do so, the policy action will be BYPASS, since it is an isolated frame within a passed website.
