@tsayen we rely heavily on this library for https://carbon.now.sh, and it seems that Chrome 72+ is beginning to have tainted canvas issues. Would you be able to release a fix for this issue? Or is there another person who would be able to push a release?

FYI, this may however be a Chrome v72 bug (https://bugs.chromium.org/p/chromium/issues/detail?id=918460&q=tainted%20canvas&colspec=ID%20Pri%20M%20Stars%20ReleaseBlock%20Component%20Status%20Owner%20Summary%20OS%20Modified)

The ticket on chromium has been updated to the fixed status on January 10th.
