There is a bug in clearing the screen.

There is a problem with right-clicking the menu page to clear the screen and using the shortcut key to clear the screen. Currently, there is a problem in the test on `kylinos-v10sp2`. I don’t know if it is because of the system.

Start by reproducing the clear-screen actions on kylinos-v10sp2: right-click the menu page and use the shortcut key, then compare both results with the expected behavior. The issue is done when both paths clear the screen correctly and the failing test passes; no source file or test path is named, so locating the relevant code will require investigation.
