--- Comment #5 from Peter Eszlari <peter.eszl...@gmail.com> --- What is the output of: $ xdpyinfo | grep resolution I think setting QT_AUTO_SCREEN_SCALE_FACTOR only helps, when you set your screen DPI. (e.g. "192") The following should work (tested with the offical AppImage under Gnome): $ QT_SCREEN_SCALE_FACTORS=2 ./kdenlive-17.12-x86_64.AppImage -- You are receiving this mail because: You are watching all bug changes.
