Android 4.2 sure seems to be developing a reputation as one of the more glitch-filled Android release in recent memory, with issues like the embarrassing missing-December bug already prompting the release of a 4.2.1 update. The latest to be brought to our attention seems to have something to do with the new multi-user support, and it’s making graphics render with some unintended transparencies.

From what users have been able to work out, the issue only pops-up when you’re using an app through the tablet’s non-primary account. In certain circumstances, it will fail to render a screen with the proper opacity, causing the background to show through. As you can see in the example above, the user’s wallpaper and home screen icons are bleeding through to a game of Flick Golf.

Exactly why this might happen isn’t yet clear, but after a little experimentation, affected users have discovered that the problem seems to go away if the offending app is also installed under the primary user’s account.

We’ll add this to the growing list of issues we’d like to see addressed in Android 4.2.2.
