Windows Terminal crashes (Vanishes with no errors) when large font sizes are used #18182
Labels
Issue-Bug
It either shouldn't be doing this or needs an investigation.
Needs-Triage
It's a new issue that the core contributor team needs to triage at the next triage meeting
Windows Terminal version
1.21.2911.0
Windows build number
10.0.22631.0
Other Software
The bug sometimes manifests when I'm running Neovim although it's also quite common from just the terminal itself, either in WSL2 running stock Ubuntu or in Powershell on the native Windows host side.
Steps to reproduce
Open Terminal. Hit Ctrl+ 5 times to boost font size to my ludicrously large default :)
Open a text based editor, stream some text to the terminal. I can't really pin down the behavior that triggers it very well or I'd take a screen recording.
This issue has happened in the past but was fixed and vanished for a while. I had previously been tracking it in #8730
Expected Behavior
I expect Terminal not to just vanish taking my editing session, command session or whatever else I'm working on with it. This is the worst kind of failure in a terminal program IMO.
Even if it just hard crashed I could maybe at least just copy what my current state was, vanishing without a trace is tough.
Actual Behavior
Terminal vanishes with no error in mid stream, sometimes while typing, sometimes while displaying streamed text.
The text was updated successfully, but these errors were encountered:
