Hello, the reference PNG is wrong. The bottom right triangle does not disappear at all - there is no such information within the file or in the description, but it is known, that for example several versions of Opera have a bug, that results in destroying the element some specific attributeType combinations are applied too. At the time, the test was created, the Opera versions did not have this bug, therefore it was not considered, that such a bug can happen related to this test, therefore such a behaviour is not covered by the simple test rule red=wrong. Because Squiggle, typically used to create the PNGs, has bugs too related to this test, presumably someone created a PNG manually relying on the wrong behaviour of Opera later ;o) I think, this was already discussed in the SVG-WG some time ago on a f2f-conference, but obviously the PNG was not fixed afterwards ;o) Looking into the source code, I think, the test was not updated due to a late incompatible change of the recommendation (id/xml:id issue), that happened after the test was created, therefore it surely needs an update anyway, not just the PNG. Well, typically the PNGs are not very relevant for several animation tests anyway, therefore it is always the problem for the test author to indicate test relevant bugs in a simple way. However I'm not sure, if the specific bug of Opera is something, that can be considered, before it appears. Olaf
