I think the problem that the UA would be focused with is the following: var path = ctx1.currentPath; ctx2.currentPath = path; or simply ctx2.currentPath = ctx1.currentPath Both contexts could manipulate the same path and both can have different CTMs which also change independent of each other. Mixing that up could cause a huge mess. That is one of the reasons why WebKit creates copies. Greetings, Dirk
