@Steely - I haven't noticed this myself with IE 11. (Windows 8.1 64 bit).....

@Ashley, So is this a Chrome specific bug only, or an underlying problem with browsers\html5, or what.....?

Anybody else noticed this on IE?
If it can be done, someone on the web will show you how to do it!

have win7 64 bit, but the 195 release runs very smooth, ie, chrome and node-webkit so I'm very happy.

Here is a related issue I have in another thread,
viewtopic.php?f=151&t=122834

It is likely to be related. Here is the captured movie of the platform starting to jitter, when pixel rounding is turned on in the second part of the movie (also repeated in slow motion).

> @Ashley Please take a look, this has been ever since I use Construct 2, around v.162. Now using v195, still there, always has been. In Chrome, Firefox, IE, yes, also v 11. Web-Nod does not seem to help either. Sometimes some stuff seems to help, to get it less disturbing, but it never got perfect. (Also, I have no idea, what exactly makes it occur less :( )

Chrome 40 just went stable. Does this improve v-sync for anyone affected by jank?

Even if not then I think Google have a v-sync patch in for Chrome 41.

No discernible improvement, according to my test capx. Here's a screen shot result from Chrome . As you can see, over a 120 sec period, there were a few hits of vsync values up to nearly 25 ms... Chrome v38 was arguably better....

Latest stable Version 40.0.2214.91 m:

@Colludium - how about Chrome Canary which ought to have the v-sync fix?

@Ashley, Canary I tested last night as well - it was no different to the current release (perhaps slightly worse, but it's Canary...). Those 25ms vsync his all happened in the first 20 sec of running the test as well.

@Ashley, here's the image from the very latest Canary - updated this morning! I'm guessing that spike is at around 20 ms vsync...

@Colludium - can you put this info on the official bug report at https://code.google.com/p/chromium/issues/detail?id=422000? Your data on the latest chrome canary is probably useful to the Google engineers, and shows there's still an issue. (As with all bug reports remember to cover the exact Canary version and your basic system spec).
