Description Hubert Kaschulke 2022-05-16 08:04:51 UTC

STEPS TO REPRODUCE
1. Create a bigfile (15 MB or so with mixed content) and load it.
2. Search for a word (Ctrl+F)
3. Search/Replace (Ctrl+R) for a word; just do "find all" without "replace all"

OBSERVED RESULT
2. takes minutes
3. reacts immediately

EXPECTED RESULT
2. should react immediately, too, and was in a version some years ago

Please update to a newer Kate / KDE frameworks version. Search performance was improved a lot in last few releases.
