Bug ID: 362696 Summary: Poor rendering performance Product: konsole Version: 15.12.3 Platform: Gentoo Packages OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: general Assignee: konsole-de...@kde.org Reporter: razrfal...@gmail.com Konsole widget update/repaint are extremely poor.

I tried to profile it with valgrind and it looks like this: http://itmages.ru/image/view/4231589/588a6a04 Full log: https://dl.dropboxusercontent.com/u/16019144/konsole-callgrind.7z (668KiB) Also tested on 16.07.70 from git.
