gganimate flashing dark green

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() +

Try updating the gifski package to 1.4.3 from CRAN.

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

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 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.
