Bug ID: 405798 Summary: Konsole becomes unusable after a search is made, even after cancellation Product: konsole Version: 18.12.2 Platform: Compiled Sources OS: Linux Status: REPORTED Severity: major Priority: NOR Component: history Assignee: konsole-de...@kde.org Reporter: awil...@adelielinux.org Target Milestone: --- SUMMARY Let us assume we have a large scrollback buffer in a Konsole tab, from compiling a lot of packages. (I am a distro package maintainer.) Let us also assume I need to search the scrollback for a phrase. So I use Konsole's search functionality. I type in a phrase ("libjni" in this case). It scrolls to the result after a considerable amount of time, highlighting it in red. The entire Konsole process is very laggy and unresponsive (even in other tabs) during this time; even switching tabs takes multiple seconds. Even after closing the search view, Konsole continues to be laggy for at least 10 minutes until it finally finishes. All the while, the terminal tab shows "activity" (possibly highlighting other matches? not sure) even though there is no activity happening in that terminal tab. STEPS TO REPRODUCE 1. Build software in a Konsole tab. Lots of scrollback; my example had 173 MB of history. 2. Attempt a search in the tab. 3. Close / cancel the search. OBSERVED RESULT Still extremely laggy for minutes. EXPECTED RESULT No more lag after the search is closed or cancelled, even if the rest of history has not been searched yet.
