This one is a silly one.
I noticed this one in the train menu, but I guess it happens in any menu where you can both scroll and filter via a search bar.
The idea is that after searching, the scroll bar disappears, but your scroll level is not reset. Hence, if you are not at the top of the screen, you cannot scroll back to the top, but you also cannot see the top anymore.
To replicate:
1. Get more trains than that fit in the train overview.
2. Scroll down
3. Use the search bar to filter out all but the first train of the train overview
Interesting trivia:
This is also a bug in Space Engineers.
