That setting (enabling OpenGL triple buffering) does not fix the Lightroom problem with my AMD FirePro V5900 (http://www.amd.com/en-us/products/graphics/workstation/firepro-3d/5900). I'm using the latest non-beta AMD FirePro Software Suite, version14.502.1019 (dated April 2015). The hardware and software supports OpenGL 4.3 (Download Not Complete).
