Original Pull Request: https://github.com/microsoft/terminal/pull/3784

State: closed
Merged: Yes

Summary of the Pull Request

Replaced a gsl::narrow call to gsl::narrow_cast call. The gsl::narrow call used to throw when the user had custom display scaling due to a bad comparison between floating point values.

References

Possible other startup crashes. I'll update this as they're found.

PR Checklist

Detailed Description of the Pull Request / Additional comments

It's a one line fix. If you want more context, here's the full description of the problem.

Validation Steps Performed

Set my machine to a custom scaling and opened a fixed build of the WT. My WT started up without crashing and continued to operate without issues (including maximizing, minimizing, and fullscreen toggle).
