Ive noticed since the last client update (4.6.2) that disabling the timeline from showing mostly doesnt work anymore. The timeline still shows about 60% of the time. I have no idea how to submit logs for this. Super annoying when fast forwarding thru the news and trying to catch the scroll at the bottom.
Being a developer myself, I tend not to give my ideas on what the cause is, as not to send anyone on a goose chase, but I have noticed it seems to pop up if the buffer is empty. That might not be the problem, but something is still triggering it.
