terminal: grdev: schedule virtual frame events if hw doesn't support it

System Internals / systemd - David Herrmann [gmail.com] - 20 September 2014 04:46 UTC

Whenever we cannot use hardware frame events, we now schedule a virtual frame event to make sure applications don't have to do this. Usually, applications render only on data changes, but we can further reduce render-time by also limiting rendering to vsyncs.
