https://bugs.kde.org/show_bug.cgi?id=361360 --- Comment #52 from Jesse --- @Wegwerf, definitely, I could see a small improvement in framerate playback when switching to Preview vs High Quality. But I didn't see any differences, visually, in playback. Maybe I need to If

https://bugs.kde.org/show_bug.cgi?id=361360 --- Comment #51 from Wegwerf --- Dont do #2, as this messes up some existing projects. It's necessary in certain projects to switch off any implicit/internally-added transitions. Also, I regularly switch off timeline compositing

https://bugs.kde.org/show_bug.cgi?id=361360 --- Comment #42 from Wegwerf --- Jean-Baptiste, Vincent, removing the composite controls is a great idea! I always wondered what the expected behavior should be when there are opaque tracks in between in the track stack. This
