Same thing just happened to me on Google Chrome v22.0.1221.1 (Nvidia GPU).
The workaround was to disable GPU compositing on all pages (setting available on chrome://flags/)
If it happens in Chrome version > 45.x, See answer https://stackoverflow.com/a/32955808/293023 by @detale.
Use google-chrome -disable-gpu from the command line to temporary disable gpu.
