Description genepakmybags 2020-07-14 20:32:12 UTC
SUMMARY

The media frame widget, when loading in a folder of images, will flash white before the image changes. I've encountered the issue with or without image cropping done by the widget, but it will sometimes fade into a new picture just fine (generally low res). 

STEPS TO REPRODUCE
1. Place Media Frame Widget onto desktop
2. Add path to folder with images (of course, this never occurs on a single image)

OBSERVED RESULT
The image, while loading in fine, will flash white on seemingly the last frame before the image fully fades into full opacity. 

EXPECTED RESULT
I believe the expected behaviour is to just have the images fade from one to the other without the flash.
