Version 2.1.56 (07fd88dd)
Python 3.9.15 Qt 6.4.0 PyQt 6.4.0
Addons disabled (held shift key when starting Anki)
The mouse cursor is sometimes an arrow and sometimes a hand when hovering over the toolbar. Please see the gif below (if a better quality gif is needed please let me know).
I think I started noticing this either on 2.1.56 or 2.1.55. I have not tried to replicate this on other versions.
