gganimate flashing dark green

[nzgwynn]

When running this code gganimate flashes dark green. I'm not sure why. Any suggestions?

anim <- ggplot(mtcars, aes(mpg, disp)) +
  transition_states(gear, transition_length = 2, state_length = 1) +
  enter_fade() +
  exit_fade()

animate(anim)

Try updating the gifski package to 1.4.3 from CRAN.

[nzgwynn]

Thanks for your response, but still blinks dark green. I'm not the only one that has this problem.

[EconProf]

Updating gifski to the latest version has fixed the green flashing for myself and others. Did you restart the R session after the update? Going back from 0.8.7.1 to 0.8.6 was a temporary solution before 1.4.3 was released. Sorry I cannot be of more help.

When I restarted R it fixed some of the animations, so thanks!

I'm not sure why the one above does not animate, but I only used it as an example.

I think it needs a geom, otherwise it just shows the axes.
