Animated gif and http dont go well together

I have tried the new animated gifs for an online weather forecast image, but the image on screen is black 99% of the time. In the editor it shows but in all wrong colors. To get it to work i have to save the preset, but as soon as the screen is off or has been occupied by another app the image is black

Should be fixed in next beta
