White background appears instead of image

I've set up tasker to download a random image from reddit every 15 minutes. My background variable in KLWP points to location of the image (location and name of downloaded image is same everytime). A lot of times I'm running into an error that displays the background as a completely white screen on my wallpaper. The other elements are displayed normally, they in fact recognise the change in background (as their colour depends on the image). When I open the editor it displays everything normally. I've tried re-applying the wallpaper doesn't help. Is there any solution?
