Firefox and large images

Christian Weisgerber
A number of weeks ago, I reported this problem on freebsd-ports:

------->
Viewing large images has become cumbersome with the switch from
Firefox 18 to 19.  Am I the only one to notice this?

Wikipedia's high-resolution pictures of the day are great for this:
https://upload.wikimedia.org/wikipedia/commons/e/e9/Bison_skull_pile_edit.jpg

What happens is that Firefox loads the image and then does some
sort of operation that causes the X11 server to be busy for a
noticeable amount of time.  During this time the whole X11 session
hangs.  If you have a network login, you can see the Xorg process
eat all the CPU it can get.  The duration of this delay varies and
depends on the size of the image; with the one above it just took
30 seconds.

This isn't entirely new.  With previous versions of Firefox it
happened when I accidentally dragged an image.  But now with
Firefox 19, just viewing the image is enough.  Needless to say,
this is painful if you are going through a number of large images
and are forced to pause for half a minute each.
<-------

Unsurprisingly, several people have now run into the same problem on
OpenBSD.

Workarounds are setting MOZ_DISABLE_IMAGE_OPTIMIZE=1 in the environment
or disabling gfx.xrender.enabled in about:config.  (You have to
restart Firefox after toggling gfx.xrender.enabled.)

I'm throwing this out there, but users shouldn't really be required
to invoke magic incantations.

You'll also see the memory footprint of the Xorg process climb to
the ceiling during that period.

I've seen that too for a long time, and what's most annoying imho is that
it also does it for large images scaled down with small width= and
height= values in the image tag.

Since afaik the X server offers no services to help scaling down the
image, I didn't understand the point in firefox allocating the full
size pixmap (or even several copies of it) in the X server.

But yes, dragging may make sense. So ff may indeed be copying the full
size image fo one of X cut buffers, which have the ability to contain
stuff other than text...

I see the samething with landry's wip firefox 20.0 from April 2nd.
MOZ_DISABLE_IMAGE_OPTIMIZE=1 fixes the problem while disableing
gfx.xrender.enabled leeds to a segfault on restart.
