Environment
App: ChatGPT desktop app for Linux (preview)
Version: 26.814.41957
Session: Repro on Wayland and X11 (Ctrl+V and Shift+Insert)
Steps to reproduce
Open the ChatGPT Linux desktop app.
Copy aaa:bbb to clipboard.
Paste into the message composer (Ctrl+V or Shift+Insert).
Expected
aaa:bbb is pasted unchanged.
Actual
Only aaa remains (the : and everything after it on that line is removed).
Workarounds
Pasting aaa: bbb works; editing afterwards to aaa:bbb also works.
Pasting inside a code block (…) works.
