--- Comment #1 from Alexandr Oleynikov sashok.olen@gmail.com --- I've done some bisecting and found that this commit from upstream caused the issue: 859b526c81a2af841b5b7b28d06f3d782bccdab5 is the first bad commit commit 859b526c81a2af841b5b7b28d06f3d782bccdab5 Author: Jacek Caban jacek@codeweavers.com Date: Mon Oct 12 18:27:18 2020 +0200
kernelbase: Use conhost in AllocConsole.
Reverting it against Staging 5.20 fixes the issue, though unfortunately it also breaks Agent.exe. It's possible it's not the true culprit, as there were quite a few conhost commits before this related to console apps and setting window title for them.
