I have a bug to report in InDesign (possibly Illustrator). I have already addressed this issue in the community forum, where it has been confirmed by others, so it is not just affecting me:

There are display errors when adjusting kerning, making precise work impossible. (Kerning is intended for fine-tuning.) When setting the kerning between two characters, the spacing of other characters also visually changes. Please refer to the video for details.

This issue occurs with both optical and metric kerning, at all zoom levels, on Windows 11 and Windows 10. Even setting the display to high quality does not resolve the issue.
