I was having this issue on a work machine I had a few months ago but cant reproduce it any more on my new work laptop. Before you file the bug, you should try to profile this issue with the Gecko Profiler, It will really help the developers understand and fix the issue and I've noticed they're less likely to ignore your bug. If you need any help doing this then contact me via PM.
This update improves the features and performance of the following components:
Direct2D DirectWrite Direct3D Windows Imaging Component (WIC) Windows Advanced Rasterization Platform (WARP) Windows Animation Manager (WAM) XPS Document API H.264 Video Decoder JPEG XR codec
Specs: Win7 Graphics: Intel HD4500, with latest drivers.
Yes, same here: http://i.imgur.com/Eze8k.jpg The from NeoWin site, does not do it all the time, just occasionsally and so far no steps-to-repo, it just happens.
This canvas particle demo is really slow for me with Direct2D enabled in both Firefox 17 and the current Nightly build.
Results after doing nothing but clicking "Play": With hardware acceleration enabled, it starts out at 60fps and then gets slower really quickly. Eventually, it stops decreasing at about 8-9fps. If I disable hardware acceleration, I get a constant 60fps.

Can anyone confirm?
Same here on a clean profile.
Sorry for my bad English. Even if there wasn't a mistake.

For me it starts at 55, stabilizes at 25-26. HWA is on. Not quite as bad, but a definite slowdown.
That is horrible, it effects graphics and text. Baffling that this is not Critical / Blocking with bas schouten assigned to it.
its only affecting people who have installed the IE10 preview on Windows 7 - so not affecting too many people.
