Subject: - Flush before updating the timestamp of a texture heap from a bound texture.
X-Git-Tag: mesa-7.8~9534
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=96035d54f3c223e6d2f6dea79fb68dbfb2b74f0a;p=platform%2Fupstream%2Fmesa.git

- Flush before updating the timestamp of a texture heap from a bound texture.
- Flush before using a new texture or before disabling a texture unit,
  because savageFlushCmdBuf can only update the timestamp of the last
  used texture. This fixes corruption in quake2 with single-textured
  lighting.
