Changing the test to NOT bind a framebuffer, essentially commenting out from tests/spec/arb_framebuffer_no_attachments/atomic.c the block that binds an attachmentless FBO: glBindFramebuffer(GL_FRAMEBUFFER, fbo); /* Setup default width and height. */ glFramebufferParameteri(GL_FRAMEBUFFER, GL_FRAMEBUFFER_DEFAULT_WIDTH, piglit_width); glFramebufferParameteri(GL_FRAMEBUFFER, GL_FRAMEBUFFER_DEFAULT_HEIGHT, piglit_height); /* Check that fbo is marked complete. */ if (glCheckFramebufferStatus(GL_FRAMEBUFFER) != GL_FRAMEBUFFER_COMPLETE) piglit_report_result(PIGLIT_FAIL); prog = piglit_build_simple_program(vs_source, fs_source); /* Check that there are no errors. */ if (!prog || !piglit_check_gl_error(GL_NO_ERROR)) piglit_report_result(PIGLIT_FAIL); produces the exact same error, i.e. this error is independent of FBO no attachments and for that matter FBO's. The bug source is likely to be a cache flush issue that manifests on atoms() only. Changing the reset_count() implementation to instead use glBufferData (creating a new BO) makes the test pass.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
