Summary: Strange drawing around models in r600g in SC2 Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: ace@sannes.org

When playing a game of sc2 under wine, some models have a white sphere around them.

This started happening after commit: commit 43bdabd47d98975b56a759954fb5f37d2942c101 Author: Brian Paul brianp@vmware.com Date: Wed May 18 16:19:06 2011 -0600

mesa: fix vertex array enable checking in check_valid_to_render()

In particular, this fixes the case where a vertex shader only uses generic vertex attributes (non-0th). Before, we were no-op'ing the glDrawArrays/Elements().

This fixes the new piglit pos-array test.

NOTE: This is a candidate for the 7.10 branch.

I will attach two images, one where the commit is reverted.

My hardware is as follows: ATI Technologies Inc RV770 [Radeon HD 4870]

Using r600g on gentoo ~amd64, with a 32bit chroot with r600g also.
