Every time I start up Kdenlive in Ubuntu 19.10, the icons all seem to be different. If I'm dark/darker, I need to switch my theme to blender, bright, or neutral (and then switch it back to what I want). If I'm blender/bright/neutral, I need to switch to dark/darker (and back). How do I make it so Kdenlive looks the exact same as when I last shut it down?
