Sounds like this showed up before my recent work, but I think I might have seen similar problems while working on atomic watermarks; the issues I was seeing were because the initial hardware readout could leave primary->visible set to true even when the CRTC was off. My series (which is still under development) contains this patch to fix that: http://patchwork.freedesktop.org/patch/59564/ Does applying that help with the problems reported here?
