Summary
Copy and paste does not work properly in the AI Assistant panel on Linux (tested on Ubuntu 24.04 with GNOME Wayland, but also experienced on other Linux distributions).
Text can be copied and pasted within the AI Assistant chat itself, but not between the AI Assistant and external applications.
For example, copying text from the AI Assistant and pasting it into another application does not work. Similarly, copying text from another application and pasting it into the AI Assistant does not work.
Copy and paste work normally everywhere else, including other parts of Unreal Engine. The issue seems specific to the AI Assistant’s embedded browser.
