title: HTML5 canvas issues on Android 4.1.1
body: <p>Now that Android 4.1.1 is out there on some phones I noticed that issues start to pop out using default browser and this OS.</p>
  
  <p>In my case I have an application that uses web views (meaning default browser) and a lot of canvas.</p>
  
  <p>I want by having this topic that everyone to post found issues and solutions if you know one.</p>
  
  <p>I will start with:</p>
  
  <p><strong>Problem:</strong> duplicated canvas 
  More info at: <a href="http://code.google.com/p/android/issues/detail?id=35474">http://code.google.com/p/android/issues/detail?id=35474</a>
  <strong>Solution</strong> Canvas parent element should not have css property "overflow" with value "hidden"</p>
  
  <p><strong>Problem</strong> Canvas drawing looks pixelated

  <p><strong>Update</strong> (3 Sep 2013): duplicate canvas issue now appears on Nexus 7 having Android 4.2.2 and/or 4.3
  Also you may want to know that "duplicate canvas" issue happens only if you have "Force GPU rendering" enabled for your device.</p>
