Chrome on OS X Yosemite Producing Garbled Graphics

A couple of weeks ago Chrome started producing unusably garbled graphics for me, under OS X Yosemite 10.10.5.

It's perhaps easier to show than to tell. For instance, Gmail looks like this:

...seems like it may be some sort of interlacing glitch, as if I adjust the window size I can get vaguely coherent things to display, such as:

I haven't changed any settings in Chrome; the issue seemed to appear at random. Neither rebooting the computer nor restarting Chrome makes any difference. Other browsers (Safari, Firefox) work fine, as does every other app on the machine. The problem seems to be specific to Chrome.

Is there anything I can do to get Chrome usable again?

Edit - My chrome version is:

I'm pretty sure that says "46.0.2490.71".

I believe this was related to Chrome's hardware video acceleration feature, and has been fixed. I had the same issue with an external monitor attached to a USB DisplayLink adapter. After updating to Chrome 46.0.2490.80, the bug (#527556) was resolved.
