Do something that would normally result in change of the cursor, it won't change until moved.
(Easily) noticeable in combat.
Repro:
1. Start a battle with at least 2 units
2. Get close to the enemy
3. Use up your attacks on a target with unit A, the cursor should show you that you can't sttack again
4. The game switches to unit B
Observe that the cursor still says you can't attack - but will update properly if moved.
