Description dutch.bull.cet 2016-12-27 15:25:56 UTC
every time a clip is played in the timeline the cursor will stall and jump back in the timeline when the cursor is at the end of the timeline at the right side of the monitor, creating an annoying effect since the clip monitor is above the same angle of the user interface. In former kdenlive versions the cursor moved ''outside'' the screen or smootly followed at a distance.

I really can't understand your explanation, please record a video. My timeline cursor is working as intended here.

Using my magic glass bowl I could imagine that the OR refers to the *scrolling* behavior of the timeline. But please take my supernatural interpretation powers with a sack of salt.

At some time, the horizontal scrolling behavior has changed for when the timeline playhead reaches the right end of the timeline window. It used to be smoothly scrolling with the playhead staying away from the right window border. Now it's jumping by large chunks.

I'll update the report title to something more descriptive.

Many performance issues are solved in the meantime and you can change the playback resolution to have even a smoother playback. 

Please try with the current Kdenlive AppImage version 20.08.1 https://files.kde.org/kdenlive/release/
