sample project that uses the file mentioned in description

When you hit a spacebar (or button in the Monitor panel) to pause the video, the cursor actually progresses several frames further (usually +5 frames). This makes precise editing really hard.

How to repro:
I believe it should work on any video file. This is a sample file (https://drive.google.com/open?id=0B3qmW8qhMR-OYmRVZkFDbmJmd1k - 44Mb). Just put it on the timeline, try to play and pause and look at current position. For example, if you press spacebar at 00:00:07:08, the final position will likely be 00:00:07:13 and you'll see non-smooth video at this moment like it skipped several frames.

I'm currently on kdenlive-16.12.2 and mlt-6.4.1. I've recently upgraded from kdenlive-16.04 and mlt-6.2 where pause worked as expected.

Actually, it could be reproduced on any project, even a simple one with just a color clip. Pay attention to the current position when you press pause.

Still reproducible with the latest 17.08.2.

Please try with the actual Kdenlive Appimage version 18.08.2
Run the Appimage from the terminal (press CTRL + ALT + T). Move to the AppImage folder and run the .AppImage: ./Kdenlive*.AppImage

It seems that this report is related to a very old unmaintained version. A lot changed since then (e.g. the timeline got a rewrite) 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/)
