Hover tooltips in full screen mode cause the current screen to switch

[cch1]

On MacOS when in full-screen mode, mouse hover tooltips cause a switch to another desktop.

The problem does not happen when I'm not in full screen mode.

Expected behavior

The current screen should be stable and the tooltip should appear as a overlay.

Actual behavior

The screen briefly (< 1s) switches to another (new?) screen on which the tooltip is visible and immediately switches back to the emacs screen.

Steps to reproduce the problem

Enter full screen mode, with a window open on a Clojure buffer with CIDER enabled. Then hover on a symbol with tooltip (docstring) content.

I can reproduce it with emacs -q.

Setting (setopt tooltip-mode nil) in the init file is a workaround to fix the issue.

So that's some regression in Emacs 29.4?

Not sure when it's started, I use emacs 30 and I have tooltips turned off since forever :)

[rrudakov]

Looks like it's an emacs bug. Can be reproduced by evaluating (tooptip-show "Hello").

I noticed the same thing happening since #3725.

This problem is still happening for me with emacs 29.4 (latest brew cask install) and cider 1.16.1.

I'm having the same issue; (tooltip-show "Hello") only opens up a new frame for me if cider-mode is enabled in a window. If I disable cider-mode, the issue goes away.
