Example URL:

Steps to reproduce the problem:
1. Open a tab
2. Carry on opening tabs until at some unpredictable point....
3. Whoa! The browser barfed video memory all over the place.

What is the expected behavior?
Expect pages to render normally sans-barf.

What went wrong?
Display is chunked into random snippets from both current and previous tabs, even x-domain. All kinds of weird voodoo happens when you try to interact with the page. Example video: https://www.youtube.com/watch?v=RBpzGr9oOBw

I've seen it happen on twitter, amazon, gmail, motherearthnews so doesn't seem to be tied to markup of any kind.

Chunks are always rectangular. Seems like the rectangles are dimensioned in multiples of 8, between 64 and 256 pixels (see attached screenshot and measure the edges of the blue chunks, you'll see 64, 127 and 256 pixel lengths.).

Screenshot also shows data from the previous URL for that tab being displayed at the same time as data from gmail (the previous URL was the page you get sent to when you click 'more info' from the Aw Snap page, which is another symptom).

Happens unpredictably, but seems to happen when I open a tab if it's going to happen at all. i.e. doesn't happen mid-browse.

I disabled all my extensions and restarted Chrome - still happens. Haven't rebooted machine yet. (iMac with 16Gb RAM, ram is reported as "OK" in the OSX system report). El Capitan.

Not sure what other diagnostic info would be helpful.

I have been doing a lot of dev with canvas, raphael, leaflet this week. But surely that wouldn't interfere between browser restarts.

Good luck!
