I suspect you're using MacOS? Chrome/Safari on MacOS perform horribly slow on some of these demos. CoreGraphics seem to be the culprit.



For some reason I'm getting horrible crashes on my app (has worked great for months. Still works great on Linux and Windows) since chrome switched to gpu rendering for everything. I haven't found the issue yet but it's really odd.


Did you already try to update GPU driver?

I had really bad crashes (high pitch noise, bright white flash, driver killed) on Firefox 4 and Chrome 7 when they started to use HW acceleration and problems went away after the update.

Though this was on Windows 7, no idea about OSX.


No luck on that, I checked and there was in fact a graphics update but that didn't affect the behavior. My next step is to try to figure out what is causing it to make a bug report.
