Mathias Agopian 3a3cad30c4 Don't call hwc set() if there is nothing new to do ... there was situations where SF's main loop would run (as if there was an invalidate), but the dirty region was empty (so no new buffers were retired). In this case we return early and don't swap, which would cause drawing artifacts. Bug: 5476838 Change-Id: Id3b7bf4b7aabec7919c50d9278eb2165973a4c3d		2011-10-18 17:39:09 -07:00
