I am having issues with google chrome not rendering svg with an img tag. This happens when refreshing the page and initial page load. I can get the image to show up by \"
On problems try to open the images first with a program that is capable to read svg-images.
If that fails, then the svg-image is somehow corrupted.
I had that case and copied the svg-paths in a new svg-image and adjusted all details of the svg-tags.
I never tested the reason that it was not rendering but suppose that some invisible special signs caused the render-error. Getting sometimes files edited on Mac I had this issue in other context already.
