Originally created by @kasper93 on GitHub (May 13, 2020).

Environment

Windows build number: 10.0.18363.815 (fun fact, PS actually reports 10.0.18363.0)
Windows Terminal revision: 88ed94d2acea5f1274800378e9d7662de9015c28

Latest cygwin with latest openssh client,

So I did update my terminal and it broke my workflow with tmux.

Steps to reproduce

  1. Run tmux (I use it in remote session over ssh)
  2. Split panes, add some windows.
  3. Zoom pane, change window in tmux
  4. Resize Terminal window

Expected behavior

Everything redraws correctly and doesn't crash.

Actual behavior

  1. Things doesn't draw correctly. Generally it is broken, not much to explain. Some things are drawn, other doesn't.
  2. Terminal will crash resize its window with tmux open. Maybe not instantly, but text blinks during resize, some disappear and eventually will crash. More panes probably will make it crash faster.

Since it looks like you've built terminal at a specific commit, I have to assume you've got Visual Studio and can help grab a call stack or logs from the debug build. Would you mind?

Regression is since commit 7ae34336da both broken rendering and crashes stared with this commit.

In release build it fails here:
b4c33dd842/src/buffer/out/textBuffer.cpp (L277)

In debug it is very slow to resize window, but it crashes still:

Interesting. This has the same callstack as #4907.

Are you displaying wide glyphs in tmux?

Which one are those? I use zsh with powerlevel10k theme. And indeed with bash without fancy things it works fine. Also I have status indicator on the right side. And this seem to mess with rendering.

That's really interesting! Thanks for the info.

Would you share some of the glyphs that are in your powerlevel10k theme?

I'll mark this as a /dup of #4907 in the meantime -- same call stack, same symptoms, same repro (go wild on resizing with garb in the buffer)
