Publishing an issue takes a long time in Navisworks
In Naviswork, under the "Output" tab, when you click the Image button, a configuration menu will appear. When we publish an issue to the add-in, we use the settings contained in that window and we only enforce our own image size(Currently 1024x1024). Your issue seems to be related to either the fact that there's a very high value set in the Anti-aliasing option or the renderer is set to Autodesk. To improve the issue publication time, simply set the Renderer to "Viewport" and the anti-alisaing to none, 2x or 4x (See screenshot below for details). This should greatly improve the publication time of the issues.
