SUMMARY

Desktop effects -> Zoom -> Enable text cursor tracking
QT_LINUX_ACCESSIBILITY_ALWAYS_ON=1

This option makes sure that the cursor is always in the zoomed area and therefore always visible to the user when typing.
It does this by keeping the cursor in the center of the zoomed area. This works fine but makes the zoomed area move with every cursor movement.
Is it possible to add a setting that makes the zoomed area only move when the cursor reaches a certain margin (for example 10%) from the edge of the zoomed area (top/bottom/left/right)?
And that the percentage for the margin can be changed. This could be one setting for all sides or one setting for each side.


STEPS TO REPRODUCE
1. Enable desktop zoom and Text cursor tracking
2. Zoom in
3. Open Kate and start typing
