Public bug reported:
My symptoms seem to be caused by what might be a timing issue, I think,
(but I could be wrong). They are the following:
This is on a new box with maverick, and I did not get to test it with
older versions.
The display goes through times where freezes, and does not update until
after a few seconds, or until the mouse is moves. It will continue doing this
for a short while, and then return to normal, and then after a longer time,
come back
the whole display, including the cursor freezes for a few seconds
sounds pause, and jump around, playing fragments that where already
played (and I can't be sure, maybe parts that come after). I had one time where
it was only sending sound from an app in short bursts where I was updating the
display.
scrolling in Firefox is weird, and I had it happen once in Konqueror too,
where it will not update when scrolled, but hover able elements, like links
would appear over the old display.
I once updated a virual box window by activating the window, and moving
the cursor across it. It acted like the scan line was attached to the cursor.
This happens with the i915 driver with and without modesetting
