I recently downloaded
IntelliJ IDEA 2023.1 (Ultimate Edition) Build #IU-231.8109.175, built on March 28, 2023
In a previous version I used to be able to hit "Ctrl+L" to clear the terminal buffer. That no longer works.
If you right click in the terminal there is an option menu with an item for "Clear Buffer Ctrl+L" but it is greyed out.
Is there some setting I am missing?
This is related to this bug report: IDEA-289979
To fix it:
terminal.use.conpty.on.windows
Make sure the checkbox is unchecked. Click Done.
That's it. Any newly opened terminal will be able to be cleared now.
