Yes, but please understand I am using the default build flags for Emacs
(just plain ./configure + make) and the giflib version Emacs 28 is using
is the one shipped with latest msys64. In contrast, for Emacs 26.3 I
already use a preinstalled distribution, which may not have the same
version of giflib and may have been built with different flags.

In any case GDI+ is faster than both of them on my system and, while
slower than the desired 0.03 s / frame specified in the GIF file, it
still looks ok.
