Console header briefly flashes periodically (randomly) since "elapsed" time was added to it

This happens on the Windows platform whenever the Console view is visible and an application is running, which causes the elapsed time to be updated every second. It seems to have been introduced (or it has become a lot more visible) since #1527 .

The "flash" this causes is quite annoying as it often occurs in your peripheral view when reading code in an editor window.

Video showing the issue, the console header briefly becomes a blank line:
