1a339b6c71ebab6e1a64f05b2e133022d3bbcd15 is the first bad commit commit 1a339b6c71ebab6e1a64f05b2e133022d3bbcd15 Author: Stéphane Marchesin <marcheu@chromium.org> Date: Wed Jun 22 17:02:21 2011 -0700 st/mesa: prefer native texture formats when possible. If possible, we want to match the hardware format to what the app uses. By doing so, we avoid the need for pixel conversions and therefore greatly speed up texture uploads. :040000 040000 6f6f68f2559303df0e7041dc1190cd1587557753 a353f28889dc64549acc3933edc12082e5d21a5a M src bisect run success
