Just recently noticed this, and after a bit of research, noticed that the new update did this. On other browsers, everything looks just as usual. Safari:
Chrome 50
Since this is not Tumult’s fault, is there a workaround? Or do we have to wait for google to fix this?
Update May 2: To workaround this issue, check 'Position with CSS/Left Top' in the Document Inspector and re-export.
I bet if you add your element to a group, expand the edges of the group, and blur the group instead of the image itself you'll fix the image issue you're seeing.
When I download the latest from Chrome's site, I only get 49.0.2623.112. I have a feeling you're part of a test group that gets Chrome updates early in a sort of staged rollout (which I can't confirm from a quick search). What is the exact version your computers are updating to?
FYI this is a chrome bug. The dev/canary channel has a fix, but it doesn’t appear complete. The workaround of turning on CSS left/top positioning in the document inspector is the best course of action at this time if you encounter the bug.
