Originally created by @riverar on GitHub (Nov 21, 2019).

Windows 10, 1909 10.0.18363.476
Windows Terminal 0.6.2951.0

Repro steps:

  1. Open Windows Terminal on display 1
  2. Unplug display 1 and replug
  3. Observe:
    • Windows Terminal dimensions have changed
    • Windows Terminal titlebar, control box, and window border are transparent/missing
    • Windows Terminal tab overflow no longer works correctly (i.e. starts overflowing before reaching the end of the titlebar)

This affects users in KVM scenarios.

This might be related to #3446. The exact effect is not the same, but it's also caused by the monitor be unplugged and plugged in again.

I've got a feeling this was maybe improved by #3394, though I can't really be sure. I'll leave this open just in case it does end up being different, though @j4james you're definitely right about the unplugging repro being similar.

🤞 hopefully this just goes away in 0.7 🤞

(I'm putting this on the 1912 milestone to make sure someone follows up after 0.7 is released)

I'm now running a dev build to reproduce, will take a few hours/days to crop back up (if present) as a reboot resolves this issue temporarily.

I suspect this bug is an artifact the longstanding system compositor bug dealing with resize synchronization (@clarkezone has more details).

The system compositor has a workaround (19H1+) to prevent this from happening:
remember

But perhaps it's affecting Windows Terminal in another way.

@riverar Is there any chance this was fixed by v0.7 (which should be available now)?

@zadjii-msft Am monitoring. If this is the bug I think it is, it will take an indeterminate amount of time to reproduce. Will follow up as soon as I can.
