Recently, we’ve covered about Chrome showing black screen when you minimize or maximize, you need to disable hardware acceleration in Chrome browser to fix the issue, Chromium team is working to fix it.

Yet another issue that’s on Google’s radar and not yet fixed is this: In Chrome, on some websites like Facebook, Twitter and Chrome Web Store, suddenly an infobar appears on top and shows this error ‘ ‘Rats! WEbGL hit a snag’.

These errors have increased recently and the bug -‘”Rats! WebGL hit a snag” error showing up more often than in the past’ indicates Android and Mac versions of Chrome were affected, but we can confirm we received this error on Windows also.

Clicking on ignore or Reload makes the error to go away temporarily, but it can reappear later. Disabling WebGL fixes the error, here is how you can do that.

  2. Search for WebGL 2.0 and select disabled.
  3. Relaunch Chrome browser.

Update: WebGL 2.0 flag has been removed by Google and its no longer available in Chrome 63.
