Yes, for certain definitions of word "fixed".

The good:
* scrolling a presentation with animated GIFs is smooth
* moving animated GIF within slide with keyboard works fine

The bad:
* hovering over animated GIF in editing pane still causes LO UI to lock-up for
some time (UI repaint takes seconds and happens line by line). As long as GIF
image is not hovered over by the mouse cursor, LO runs fine.
* moving around animated GIF with mouse within the slide still is a game of
patience (due to hovering) and now causes X11 to cause serious CPU load instead
of LO. Still it is much better than it was.

And the ugly:
* closing LO Impress after an animated GIF has been hovered by the mouse cursor
almost always ends with a LO crash. One of crashes managed to output a hint on
"double free or corruption (fasttop)" in terminal.
* it is not always crashing while running under valgrind.
