I was investigating getting SIGSEGV when loading the Minecraft with Prism Launcher and X11, and I found that
XMODIFIERSenvironment variable is missing, causing the XIM to support only basic input styles.This PR fixes that and adds debug logs to help users/developers investigate the issue in case of a crash (related or not related to this).
Also, this PR fixes the issue where IME dialog is at wrong position. (I'm unsure if it works well on other users)
I will remove debug logs if those are not needed.
EDIT: I tested this code with caramelChat mod with compiled binary. I'm using Debian (Trixie) and GNOME with X11.
