GNOME Bugzilla – Bug 711168
When clicking to add a keyframe, the keyframe gets created a few pixels lower than the actual mouse cursor position

This is quite annoying as it is impossible to create a "line" of keyframes, they always get shifted/drifted downwards everytime you create one, so there is no precision in creating keyframes. Possibly affects keyframe deletion too.
This partially fixes this bug: commit 54408036318a624b4ccade928dcc4fdbe93b74b9 Author: Alexandru Băluț <alexandru.balut@gmail.com> Date: Wed Feb 26 17:57:21 2014 +0100 elements: Fix video clips keyframes and lines vertical position Fixes https://bugzilla.gnome.org/show_bug.cgi?id=711168 Another commit should make sure that when a keyframe is created by clicking a line, only the x coordinate of the click event is considered, with y being calculated from the two points defining the clicked line and the x of the click event. Otherwise, given the fact that the line has a width of a few pixels, the keyframe is not created on the line but possibly a bit upper or lower.
The current behavior after your commit is already a very nice improvement, thanks Alex! I guess you're leaving this open/assigned for now because you want to continue with what you've proposed in your comment.
