Re-enable WebGL without restarting Chrome

Question

When Chrome stops WebGL and gives you the following error (in a yellow banner on top of the screen): "Rats! WebGL hit a snag...", and reloading does not work (WebGL is still not re-enabled), is it possible to re-enable WebGL without restarting Chrome?

Context:

• Chrome disables WebGL probably because it requires too many resources: I ask it to display 400,000 billboards on Cesium, for those who know what this is.
• I know how I could reduce the resources my app asks for, but actually I am exploring its limits for testing purposes. So I am going to make Chrome disable WebGL a lot of times, and I do not want to restart it everytime it disables WebGL.

My configuration:

• Chrome 35.0.1916.114 m
• Windows 7 Pro 64 bit.

Solutions explored:

• I already tried to open a new Chrome window, it does not work. For the moment all I can do is close all Chrome windows and restart it.
• I already tried to put --ignore-gpu-blacklist in the Chrome shortcut (even if I understood this is for Windows XP, right?).

Hope I was clear enough. Thank you for your help.

I was having the same problem and I just found a solution. It sounds like this didn't work back when this question was posted but, it works now!

Refreshing the page doesn't work. If you clicked a link from a different tab to open the tab the crashed, clicking that link again doesn't work. You have to open a new tab and paste in the URL of the page that you want to reload.

I'm guessing this is due to chrome threading... by opening a brand new tab, you create a new thread instead of using the existing one.
