This update allows CEF to render in Linux environments that lack an X11 server, such as desktops running Wayland without XWayland, and headless environments such as containers. Note that this change removes the existing Linux binaries for CEF and replaces them with a new set of binaries, hence the large number of changed files. #jira UCS-5194 [FYI] Mattias.Jansson #rb Luke.Bermingham #preflight 63355bc1f418a1071a5209de [CL 22260825 by adam rehn in ue5-main branch]
