The VSEDGEJITTER variable switches the display of edges to be viewed with several linear streaks, as if the edges were sketched using a pencil. The value defines the number of jitters which can be:
Value
Description
1
Low jitters
2
Medium jitters
3
High jitters
A negative value turns off the sketch effect, but the variable continues to store the number of jitters.
Note: An existing visual style is not changed when the system variable gets a new value. Temporary visual style will be created as a clone of visual style assigned for current viewport.
