I am using Linux Mint 19.3. Just installed Kdenlive. I see the title clip window is so big...

I dont see any option to resize it. I tried to click on edges. Its not resizeable. Can anyone tell me how can I resize and fit to window?

seems an issue like the one reported on Windows... https://invent.kde.org/kde/kdenlive/-/issues/412

I used to have the same problem, especially with the latest flatpak version. I found that simply using Alt+F8 and scrolling the mouse lets you resize it and get you going with your titling
