Description

Over the summer, Future Me (hopefully) added support to wlroots for intelligently and dynamically changing when, relative to a previous frame, a compositor starts to render. It's better to start it later for lower latency but that comes with a risk of missing the deadline if rendering takes longer than expected. The work includes an API for specifying when rendering should start and a "stock" algorithm for predicting a good value for that parameter, along with some necessary infrastructure in wlroots. I'll talk about how the project went and what came out of it.
