I have reported it upstream: https://core.tcl-lang.org/tk/tktview/132dd3d350\r\n\r\nHowever, I would like to see if IDLE can make a simple change to avoid the issue, in case Tk Aqua does not address it soon. Moving a toplevel far offscreen to hide it while configuring its contents seems improper, as opposed to something like withdrawing it. Hiding the toplevel to avoid visual artifacts is probably no longer necessary, except maybe on something sufficiently slow like X11 forwarding. IDLE also does not make a similar effort to temporarily hide the toplevel for calltips.\r\n\r\nSo I would suggest making this `wm_geometry()` call only when `acw._windowingsystem == 'x11'` or at least `acw._windowingsystem != 'aqua'`.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-104591\n* gh-104596\n* gh-104598\n* gh-104599\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/chrstphrchvz","@type":"Person","name":"chrstphrchvz"},"datePublished":"2023-05-15T07:51:02.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/104499/cpython/issues/104499"}
