Can confirm using Ubuntu 18.04 and gedit 3.28.1. This needs to be reported upstream as probably not an Ubuntu issue.
See https://wiki.ubuntu.com/Bugs/Upstream/GNOME. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gedit in Ubuntu. https://bugs.launchpad.net/bugs/1800179 Title: Search in recent files list only works with lowercase letters Status in gedit package in Ubuntu: Confirmed Bug description: When clicking “Open” and typing to search the recently opened files, any search involving uppercase letters fails to return any result, even if files with uppercase letters in their file names have recently been opened. Searching for the same file names, but using all- lowercase letters, does yield results (see attached screenshot). So it seems that gedit converts the recently used file names to lowercase before comparing to the search term, which is incorrect.
