MacBook Pro 15", late 2016 touchbar model. macOS 10.13.1. Sublime build 3154
Whenever the GPU switches from integrated to discrete, sublime’s framerate collapses horribly. This holds until restarted, even if the machine reverts back to the integrated GPU. I can trigger this 100% reliably by launching any application which requires the discrete GPU (e.g. Photos is an easy one) after Sublime is already open. Scrolling and editor interactions go from buttery smooth to extremely jerky, with noticeable tearing and even sometimes lag (could be another bug; haven’t isolated that one yet). Framerate is 100% reliably smooth when remaining entirely on the integrated GPU.
