Original Pull Request: https://github.com/microsoft/terminal/pull/4829

State: closed
Merged: Yes

Summary of the Pull Request

Pretty straightforward. When we get a WM_DISPLAYCHANGE, that means the display's DPI changed. When that happens, resize the drag bar, so that it'll reflect the new scaling.

References

I'm doing this to unblock #4778

Man I've changed the DPI of my displays so many times in the last 30 minutes. I draged the window across a bunch of DPI boundaries too.
