Bug ID: 385276 Summary: Krita canvas lags on larger displays on macOS Product: krita Version: unspecified Platform: Compiled Sources OS: OS X Status: UNCONFIRMED Severity: normal Priority: NOR Component: general Assignee: krita-bugs-n...@kde.org Reporter: bernhard.li...@gmx.org Target Milestone: --- Krita's graphics output on macOS is relatively slow, and it is very slow on 5k iMacs. This seems to be related to QT's QWidget implementation on macOS. And this is probably a well-known problem. If not, this ticket can keep track of infos about QT's state of things. Two useful pointers I found: https://forum.qt.io/topic/59578/rendering-performance-problems-on-imac-with-retina-5k/24 https://bugreports.qt.io/browse/QTBUG-44228 As QT's OpenGL compositing internally happens with and without Krita's OpenGL canvas, switching to Krita's raster canvas does not make a difference. -- You are receiving this mail because: You are watching all bug changes.
