Disable input sources pop-up in macOS 14
Since the update to macOS 14.0 Sonoma, I every now and then get the following pop-up while typing. At first it is just the blue circle with "US":
When I click on it, the white part with "DE" appears:
As these are the two input sources I have installed, I assume this is to switch between them.
This pop-up occurs in different applications, both from apple (e.g. in Terminal.app) as well as in third-party apps (e.g. TeXstudio.app), so I assume this is a feature from the operating system rather than from specific apps.
Is there a way to disable it?
My settings about input sources look like this:
Uninstall all input sources but US did not solve the problem either. The pop-up will still occur even if clicking on it does not give any options to switch the language.

I finally found a solution thanks to @bogdanw at https://stackoverflow.com/a/77256214/2777074
The idea is to create a file called UIKit.plist with the content:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>redesigned_text_cursor</key>
<dict>
<key>Enabled</key>
<false/>
</dict>
</dict>
</plist>
This file should then be placed in /Library/Preferences/FeatureFlags/Domain and the system restarted.

Hi, I had the same issue, so ended up writing a small open-source utility that switches input sources instantly on FN press: https://github.com/tonku321/fn-lang-switcher
