When enabled it changes the output file in render dialog from /home/managor/Videos/untitled.webm to /home/managor/Videos//untitled.webm. This effect requires program restart to manifest after saving the settings. Also enabling it doesn't do anything to the default folder, it still takes what you have inputted into the textbox whether or not it's active and writable.
Here are 2 videos to visualize the (apparently 3) bugs Doubleslash bug https://webmshare.com/YeK4N Having the button on or off has no effect and a second doubleslash bug https://webmshare.com/YeK4N
Having the button on or off has no effect and a second doubleslash bug https://webmshare.com/OXm4Y I messed that up
Ok, so I had a look at the issue you describe. I will check the double slash issue. But the main problem is that you misunderstood the UI. When you go to Kdenlive Settings > Project Defaults you change the default settings for new projects. If you want to change settings for your current project, you need to go to: Project > Project Settings There you can change the project folder for your current document and it will move existing temporary files to the new folder.

That was only to show that it didn't manifest until I restart the program. The real issue was that having having the "Custom project folder" button on or off didn't make any difference. When having it off, the program didn't default to anything.
Oh, I see. Sorry there were too much issues described so I didn't catch the real problem. Will fix that asap.
