Vscode : compile warnings disappear from terminal window

[mikeselectricstuff]

New to VSCode, slowly getting there but can't figure this out...
During build, you see all the compiler warnings etc. scrolling up the terminal window, but when it completes successfully, the window gets cleared, and just shows the memory usage summary.

How do I either get back to the warnings produced during compile, or stop it clearing the terminal window when it's done ?
