This is a bit of a more unusual bug to report:
The screenshot above is unedited - the black box is rendered by the Stack Exchange application.
Phone: Samsung Galaxy Discover running Android 4.0.4 (ICS)
Update: 1.0.6 is now out.
Good news everyone!
This has been fixed as of version 1.0.6 which should be hitting the Play Store within the next 6-8 hours.
Technical description follows for those inclined to read it.
Some backstory first: During our alpha we noticed that scrolling quickly through answers led to a flickering black box each time the contents of the answer were displayed. In our testing we learned that this was only happening on GPU accelerated devices. When we looked into it, it ended up being a bug with how the GPU acceleration handles
WebViews which have a completely transparent background so we simply set the background on those views to be 1% opaque if the phone had hardware acceleration.
Well, it turns out that in 4.0.x there is a bug when you try to use transparent
WebViews. I learned this by attempting to take a screenshot of the application running on a Samsung Galaxy Discover and seeing that the contents of the question (which was a big black box on my phone) was actually transparent on the screenshot.
As of version 1.0.6 we don't do our black-flickering hack on devices that are running below version 4.1 of the OS.
