Environment

Windows version 10.0.18970.0.
Latest Windows Terminal build (either the available bits or locally built.)

Steps to reproduce

This is the same repro as issue 1360, which I was trying to reproduce and hit this render-related crash instead:

Install ripgrep
Open wt (Windows Terminal), running PowerShell.
Run the following from the root of a large drive
while ($true) { rg -i "foo" }

Expected behavior

The terminal continually runs ripgrep against all files on the drive. It does not crash.

Actual behavior

Eventually the process will crash. If running a debug build, you will get an Assert dialog (Abort, Retry, Ignore) and if you attach a debugger and press Retry you will see the crash is in renderer.cpp at line 642:
