[Swiping cards] New card shows content(images) from previous card briefly after swipe

After swiping (as demonstrated in the video below) the images from
the previous card flash for a little bit, which is pretty annoying and
looks ugly as hell. Any suggestions/ideas to fix this?

Example video (because it’s the only way to explain the problem)

Previously I have asked this on Stackoverflow and /r/ionic without results.

Thanks in advance!
