> Chrome did not "break" rounded corners, they are various cases in which they arent perfect, but every time someone makes this argument they just point to "search the chrome bug tracker" as opposed to giving a specific breakage
Here's an example bug where the antialiasing was screwed up:
http://code.google.com/p/chromium/issues/detail?id=20064
And here's one demonstrating the (much worse) problem that you could get completely different colours showing through, although the screenshot isn't great because it only shows a small issue, not the much more offensive result if you had a larger corner radius:
http://code.google.com/p/chromium/issues/detail?id=128
Spending literally one minute with Google would find you numerous related problems with screenshots attached.
Pretending this wasn't a problem with Chrome and related browsers is like an IE fan pretending that no-one ever really needed CSS hacks because (insert excuse here). There were numerous complaints about this for several months from practising web developers.
> They have decided not to support h.264 at a time when every developer had to already have implemented a fallback anyway, again its not broken.
If we all have to implement fallbacks anyway, why bother supporting any modern browser features at all?
They had H.264 support. They took it away. That means stuff that used to work in Chrome won't any more. It doesn't matter what words you use to describe that situation, the result is still the same.
