Slide Show: Avoid flickering between images

Post by Joe/Berlin »

Hello all,

How can I void flickering between images in a slide show? I show pictures that are mostly white and only differ slightly. When the images change, the diplay is erased before the next image is displayed, resulting in a short black "flicker", which is very annoying. Other viewers such as "feh" don't exhibit this behaviour, as they immediately overwrite the old image by the new one.

Is there any parameter that I have overlooked or does the above behaviour have to be regarded as a bug?

Cheers,
Joachim

Could you tell me which settings do you have?
