From: Zack Rusin Date: Tue, 18 Jun 2013 01:06:11 +0000 (-0400) Subject: Revert "draw: clear the draw buffers in draw" X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9542131b273d01d2c3403e6791172347cb792e34;p=mesa.git Revert "draw: clear the draw buffers in draw" This reverts commit 41966fdb3b71c0b70aeb095e0eb3c5626c144a3a. While it's a lot cleaner it causes regressions because the draw interface is always called from the draw functions of the drivers (because the buffers need to be mapped) which means that the stream output buffers endup being cleared on every draw rather than on setting.
