Fix sync issue between XFB output and UBO input For the following scenario, where the first draw writes to the transform feedback buffer and the second draw reads from the same buffer as UBO, it is necessary to end the render pass between the two draws and add a barrier. // xfb write glBindBufferBase(GL_TRANSFORM_FEEDBACK_BUFFER, 0, xfb); glBeginTransformFeedback(); glDrawArrays(); glEndTransformFeedback(); // Draw with same buffer as UBO glBindBuffer(GL_UNIFORM_BUFFER, xfb); glDraw(); Bug: angleproject:418568423 Change-Id: Ia294d174111c6104b55762590ec26056ee759b53 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/6572198 Reviewed-by: Charlie Lao <cclao@google.com> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org>
