Would not surprise me that this happens because the apps expect more RAM to be on hand, and so are not as carefully optimized for low RAM circumstances.

I am seeing something similar over at Android. Where earlier versions of the Play store app worked without a hitch on my aging tablet, now it seems to crash left and right whenever i want to look at longer lists of search results or similar. And this seems to happen when it tries to load the app icons or similarly asynchronously, meaning that i can enter the search, get a list of results, and then see the app stutter and crash as it tries to load the graphics.
