question

Hi, I have been investigating a bug in the Carmageddon app, where occasionally bringing the side-bar up on the Kindle Fire HDX 7" by dragging the tab on the right side of the screen to the left, and then pressing on another part of the screen (to dismiss the side-bar). I have also seen this on the Kindle Fire HDX 8.9". I have been unable to reproduce the issue reliably, the glitch does not occur every time the side bar is brought out. The app is a native app that subclasses NativeActivity, however I am unsure how the system sidebar could be interfering with the app if it is not a system bug. Here is a screenshot of the issue, notice the glitchy areas on the right of the screen where the sidebar can extend. These areas continue to update/refresh in time with the areas of the main display that they mirror: http://postimg.org/image/5b772ek19/ I have also seen this issue in another native app. I was wondering if anybody else had experienced this issue and could provide some insight. Thank you!
