<h1>webGL test</h1>
|
||||||
Checks if the addon also supports webGL.
|
<h2>Expected result</h2>
|
||||||
|
<ul>
|
||||||
|
<li>both webGL versions should be supported (unless you disabled it in the browser settings) - reload if one is showing "not supported"</li>
|
||||||
|
<li>upon page reload the hashes change</li>
|
||||||
|
<li>upon page reload some of the parameters change</li>
|
||||||
|
<li>the "vendor" und "renderer" (also unmasked) parameters reflect the values you chose for them</li>
|
||||||
|
</ul>
