调研方向

Start by reproducing the intermittent failure in a VSCode terminal using the listed alt-tab and terminal-selection steps. Trace the stack from CalculateWhereAndWhat through ReallyRender and ForceRender, focusing on the cursor top value versus the console buffer size. Done means the repro no longer raises the ArgumentOutOfRangeException.

Screenshot

I've seen this happening in vscode as of the last couple weeks, and it only seems to happen after alt-tabing back in and selecting the terminal again, not after the previous command:

Environment data
PS Version: 7.6.1
PS HostName: ConsoleHost
PSReadLine Version: 2.4.5
PSReadLine EditMode: Windows
OS: 10.0.22621.1 (WinBuild.160101.0800)

Steps to reproduce
  1. Use vscode terminal with PSReadline
  2. Alt tab out
  3. Alt tab back in
  4. click/select terminal again

Does not happen consistently.

Expected behavior

Throws error, but it doesn't seem to actually cause any issues, but I thought to report it since I keep seeing it tell me to lol

Actual behavior

Error occurs in terminal
