Description Tapani Pälli 2016-02-15 06:08:54 UTC
I've bisected this to:
--- 8< ---

commit 0dcd9a09d19d25bf247118b218b4b439e8df619b
Author: Topi Pohjolainen <topi.pohjolainen@intel.com>

    i965: Restore vbo after color resolve during brw_try_draw_prims()
    
--- 8< ---

If I comment out following line

"ctx->vbo_context->exec.array.recalculate_inputs = true;"

then rendering results look normal again.

Suntemple and other demos are available at:

I was able to confirm the rendering errors with SunTemple. But I also run a piglit run, and noticed that the commit fixes two piglit tests:

 * egl_chromium_sync_control
 * getteximage-formats init-by-clear-and-render

Just saying, as it was not mentioned on the commit message.

But then the piglit tests start to fail again.

issues are gone now, piglits will be dealt separately later on
