<li>glUseProgram() is now compiled into display lists (bug 23746).
|
||||
<li>glUniform functions are now compiled into display lists
|
||||
<li>Auto mipmap generation didn't work reliably with Gallium.
|
||||
<li>Fixed random number usage in GLX code.
|
||||
<li>Fixed invalid GL_OUT_OF_MEMORY error sometimes raised by glTexSubImage2D
|

when using Gallium.
