--- Comment #10 from Caolán McNamara <[email protected]> ---
This .gif is an 8 bit 1920x1080 animated gif with 382 frames in it, and indeed
on my debugging master LibreOffice when it is rendering "top" reports...

some debugging shows that in
drawinglayer/source/primitive2d/graphicprimitivehelper2d.cxx when we have an
animated gif we render each frame into a separate BitmapEx and create a
BitmapPrimitive2D for each one and the size balloons once rendering starts and
generates 382 of those.
With my proposed fix of https://gerrit.libreoffice.org/25671 to add a custom
AnimationFrameBitmapPrimitive2D which shares a virtual device among the frames
of a animated gif and moves the BitmapEx generation around to become on-demand
I then get those numbers down to...
