Originally created by @Johnlon on GitHub (Nov 16, 2020).

Environment

Windows build number: [run `[Environment]::OSVersion` for powershell, or `ver` for cmd] Version	10.0.18363 Build 18363

Windows Terminal version (if applicable): Version: 1.4.3141.0


Any other software?

Steps to reproduce

Moving away focus to another app and coming back.

Expected behavior

No corruption

Actual behavior

image

Seems to get worse as I alt tab away and back.

Not consistently happening so not sure how to provoke.

If I force a repaint by dragging over it then this repairs the view

However, if I scroll the window then the corruption moves with it so I guess the canvas data is corrupted somehow?
