Bug in isf editor

[cat]

If you are coding in the editor, and then undo multiple times quickly, lines can get corrupted, and redo doesn't recover them.

Thank you for reporting this. Could you maybe share your shader code with us? It would be interesting for us to see what happens. Maybe you can save your original version and the corrupted one. And if you could maybe make a little movie that would be great. You can send it through DM if you like.
