Is this a new/recent issue? Do you have an idea when this started exhibiting?

If you restart into Troubleshoot Mode or try creating a new profile to test, it still renders the same?

If you open e.g. www.svgviewer.dev do you see the sample orange box rendered in the right panel?

I don't recall when it started. Its been awhile. It just recently became an issue I needed to get fixed. I tried troubleshoot mode and don't recall the results. As per svgviewer, yes, there is an orange block on the right. If you're asking if it happens on other browsers, the answer is no. As I stated, this is not a problem in chrome. Whatever it is, it is 100% just a firefox issue.

I think the use cases you describe are not SVG per se, but more likely using Canvas functionality. Which is something "privacy" addons like to tweak and fuzz, and may break these sites inadvertently if they're not updated for compatibility. Troubleshoot Mode starts without loading these so should get a better picture.

If you still reproduce in that mode, and/or a fresh profile (or a separate nightly.mozilla.org that already comes with a clean slate), it's best to file a bug so that the engineers will be able to ask for logs and provide some alternatives to verify.
