When the screen is turned off, the current stack is set to -1. This causes logic in iSurfaceFlinger's handleTransactionLocked() function to fail to match the current stack, and the latest orientation is not set into the layer. This causes BufferQueue, later, to potentially set an obsolete transformHint on a created surface (such as in the case with ImageWallpaper's Egl surface, in the bug below). The fix is to note this situation and use a default value for the DisplayDevice, which should have the current orientation information. Issue #8508397 ImageWallpaper sometimes rendered in wrong orientation causing a ~30-40% drop in graphics performance Change-Id: Ibae15d73b289a8343c67f4f6bb77fdf11dd95ee7 |
