I have upgraded my Mac mini to the newest one with M4 processor (coming from an Intel i5 based one, already using Sequoia with the old one). Since then, IDLE shell has a changed GUI behaviour. When having a squeezed text the tooltip looks a bit different (not as nice and smooth as I have in my mind from the Intel system) and when I right-click on it as usual for viewing the complete text, nothing happens. Seems to be related to Tk, Qt or whatever is used here. Does anyone have an idea how to get this working again? Thanks a lot!

Here is how it looks like on macos and Linux:

Update: I have played around with a virtual machine and found out that when using conda instead of pyenv I get the IDLE behaviour I want. So something seems to be different in the installation. I don't want to mark it as solved because the issue itself is still unclear but yes, finally this is a solution for me.
