Back with a follow-up to my previous post. Doing a new post since this describes a different problem, even if it is related.
Ionic slides seem to have a real problem with images when they are different dimensions, particularly pronounced when going from a landscape to a portrait image. The problem isn’t terribly pronounced in this simple example, but it creates some pretty serious issues in my app. Notice on the below pen that as you slide to/from portrait images, previous images continue to be visible on the left edge. If you wrap the image in ion-content, the problem disappears, but that’s not an option since you then cannot scroll up and down the page if over the image.
