If font-lock is enabled, smerge-mode uses it to fontify the conflicting
regions.  See smerge-font-lock-keywords.  So perhaps the regular
font-lock debugging techniques might help you investigate this issue in
more detail.

Also, if you have some steps to reproduce it, you could also create a
bug report by using M-x report-emacs-bug.  Thanks.
