Imagine you have a view that lists upcoming events on your Drupal 8 site. There's a date filter that filters out any event who's start date is less than the current date. This works great until you realize that the output of the view will be cached in one or many places (dynamic page cache, internal page cache, varnish, etc). Once it's cached, views doesn't execute the query and can't compare the date to the current time, so you may get older events sticking around.

I'm working on a site where the editorial staff may occasionally produce animated GIFs and place them in an article. Image styles and animated GIFs in Drupal don't play nice out of the box. Drupal's standard image processing library, GD, does not preserve GIF animation when it processes them, so any image styles applied to the image will remove the animation.

I recently worked on porting over a website to Drupal that had several dynamic elements throughout the site depending on the IP address of the user. Different content could be shown depending on if the user was within a local network, a larger local network, or completely outside the network.

I just finished up a small project at work to create a basic resource management calendar to visualize and manage room and other asset reservations. The idea was to have a calendar that displayed reservations for various resources and allow privileged users the ability add reservations themselves. The existing system that was being used was a pain to work with and very time consuming - and I knew this could be done easily in Drupal 7. The solution could be extended to create a more general resource booking / room booking system.
