Looking forward to your response.
But, Anubhav, that is a workaround, not a solution. Is Adobe working to solve this bug?
What file format are you using for those images, and are they linked or embedded? Use PSD and if that is a printed brochure in CMYK color mode.
If they are linked and look good in photoshop, then uncheck GPU performance.
