sorry, a typo. nodepth-test has been failed since 2009-12-30 on i915. *** Bug 35193 has been marked as a duplicate of this bug. *** commit fc4fba52cf7e9616c70dd76b4d6bdba6582e157b Author: Eric Anholt <eric@anholt.net> Date: Tue Jul 12 10:48:40 2011 -0700 i915: Disable the depth test whenever we don't have a depth buffer. We were disabling it once at the moment we changed draw buffers, but later enabling of depth test could turn it back on. Fixes fbo-nodepth-test. Note that ctx->DrawBuffer has to be checked because during context create we get called while it's still unset. However, we know we'll get an intel_draw_buffer() after that, so it's safe to make a silly choice at this point. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=30080 verified on Pineview. |
