SUMMARY i cant believe you dont know about this, if so juat ignore. i downloaded kdenlive 18.08.2 appimage from your website. the first time i run kdenlive appimage it has a dark background and i cannot change the height of the timeline window, it just snaps back. if i exit and run it a second time, it comes up with a white background and i can resize the timeline height. if i remove the kdenlive-appimagerc file then when i run it, it gives me the dark background again but no timeline resize. i prefer the dark background with the ability to resize the timeline. i downloaded kdenlive 18.04.1 appimage and it does not have the timeline resize problem. however it changes to a white background on all runs after the first. STEPS TO REPRODUCE 1. download appimage, run, resize timeline, exit, run, resize timeline 2. 3. OBSERVED RESULT EXPECTED RESULT SOFTWARE VERSIONS i think all these versions are in the appimage (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION os is ubuntu 18.04.1 with the default gui.
settings -> themes -> breeze-dark will fix the problems but i have to do it every time i run kdenlive, it does not remember. this should be changed to minor in importance.
I confirm. I had the same problem with the new AppImage 18.08.3 yesterday.
It seems that this report is related to a old unmaintained version. A lot changed since then and it is likely that this has been fixed. Feel free to reopen this bug or create a new report if this is still happening with the latest version (https://kdenlive.org/en/download/)
