Description

Environment

Windows build number: 10.0.18362.0
Windows Terminal version (if applicable): 0.4.2382.0

Any other software?

Steps to reproduce

Can't reproduce consistently, but sometimes, when I navigate back to Windows Terminal from another window, the content of the Terminal window completely disappears and the window becomes transparent.

I'm using PowerShell Core, and I typically find that the problem occurs after running an npm script. Sometimes, if I hit up and then Enter, the previous command re-runs and the window returns to normal. On other occasions, this seems to have no effect.

Contributor guide

Research direction
Investigate the rendering code path when the Terminal window regains focus, particularly how the screen buffer is refreshed. The issue may be related to an incomplete redraw after switching away and back. Look for conditional logic that might skip rendering under certain conditions.
