works also on the desktop (Mac and Win)!

Use "the effectrate" to set the duration of the "very slowly" (sic!) visual effect.
Mentally a bit challenging, but works! :-D

Yes, visual effects are in fact blocking unfortunately!

But maybe you can use something like:
set the effectrate to 500
lock screen for visual effect
show image "burger"
hide image "shot"
unlock screen with visual effect dissolve very slowly
