Fixing Rats WebGL: If you are a Chrome browser user and have seen “Rats! WebGL hit a snag” on the error bar way too often, it can get frustrating. You try to reload the page or navigate to a new one, the error bar still shows up the next time you access a WebGL. And on the first occurrence of the error, Chrome will not be using WebGL again for the same site unless you specifically reload it. The showing up of Rats! WebGL hit a snag multiple times for different sites is not an indication of a continuous error but that you are trying to access a WebGL. This article will talk about What is WebGL?, Why we see the error Rats! WebGL hit a snag and How to fix this error. Let’s get started.
What is WebGL?
The new standard for 3G graphics on the web, WebGL is designed for the purpose of rendering 2D graphics and interactive 3D graphics developed by an American-Serbian software engineer named Vladimir Vukicevic who did the foundational work when he started working on an OpenGL prototype and leading from that Kronos Group created WebGL.
So at the most basic level, WebGL (Web Graphics Library) is an image library that enables you to create real-time rendered, interactive 3D graphics by using a different part of your computer’s brain than that usually used. What it means is that you can build advanced 3D visuals that run in a web browser in spite of the user not downloading any plugins (adds a specific feature to an existing computer programme).
Simply put, WebGL is an openware that can run without JVM (Java Virtual Machine) and is completely controlled by the web browser. It is derived from OpenGL’s ES 2.0 library which is a low-level 3D API for phones and other mobile devices. WebGL provides similar operationality of ES 2.0 (Embedded Systems) and performs effectively on modern 3D graphics hardware.
The Web browsers Internet Explorer, Google Chrome, Safari, Firefox and Opera support WebGL. And mobile browsers Chrome for Android, Android browser, iOS Safari, Opera Mini, BlackBerry Browser and IE mobile support WebGL.
What are the advantages of WebGL?
There are several advantages WebGL provides. Some of them are listed below:
- Open source: Being an open source, WebGL enables you to access the source code of the library and understand how it is developed and functions.
- Increasing support for mobile browsers: It supports a variety of mobile browsers such as Chrome for Android, Android browser, iOS Safari, Opera Mini, BlackBerry Browser and IE mobile.
- Easy setup: There is no requirement for additional setup since WebGL is integrated within HTML 5.
WebGL provides with a multitude of benefits and getting the error ‘Rats! WebGL hit a snag’ is not bound to be convenient in terms of using accessing a site as well as not being able to explore the features that it brings along with it. Why do we see the error? Let’s see.
Why do we see ‘Rats! WebGL hit a snag’ error?
When using WebGL, you may have had a problem with a site falling back to canvas rendering if WebGL is not supported or is found to have an error. The error ‘Rats! WebGL hit a snag’ shows up and clicking on ignore or reload button makes the error disappear temporarily, but it can reappear later. There are a few methods by which it can be prevented. Let’s take a look.
How to fix ‘Rats! WebGL hit a snag’ error?
There are a few ways by which we can fix the error ‘Rats! WebGL hit a snag’. We can fix it by disabling Hardware Accelerated Graphics in Chrome, or by disabling WebGL itself or we can navigate through the Chrome GPU. Let’s see how each one is done.
1. By disabling WebGL:
1st Step: Go to chrome://flags
2nd Step: Enable ‘Disable WebGL’ option.
3rd Step: Restart the browser.
This is a simple and effective method to resist the error.
2. By Disabling Hardware Accelerated Graphics in Chrome:
1st Step: Go to chrome://settings
2nd Step: Select ‘Show advanced settings’
3rd Step: Choose the option ‘Use hardware acceleration when available”
4th Step: Disable by unchecking it.
5th Step: Restart the browser.
This will ensure that the error doesn’t persist and show ‘Rats! WebGL hit a snag’.
3. Through the Chrome GPU:
1st Step: Go to Chrome://GPU
2nd Step: Search for Problems detected heading.
3rd Step: Search for Red warnings under Problems detected section.
This will help you detect the problem as to why the error message is popping up.
You can employ any of these three methods to prevent the error ‘Rats! WebGL hit a snag’. This article covers what is WebGL, What are WebGL’s advantages, Why the error ‘Rats! WebGL hit a snag’ shows up and how the error can be fixed.
