Originally created by @jasl on GitHub (Mar 15, 2020).

Environment

Win32NT 10.0.19041.0 Microsoft Windows NT 10.0.19041.0

Windows Terminal (Preview) installed from Microsoft Store, version: 0.9.433.0

Intel Core i9 9900K and Nvidia Geforce 2080 Ti (with latest driver), hardwares are powerful enough and well maintained.

Steps to reproduce

  • Upgrade to Win10 v2004 from v1909
  • Open Windows Terminal

Expected behavior

Windows Terminal should smoothy all the time

Actual behavior

When the terminal window is the active window, I experienced a visual lag, especially when mouse moving and draging the terminal window, not smoothy clearly.

When draging the Terminal window, in TaskMgr I can see the power consumption status of Windows Terminal process from very low changing to very high quickly.

When the Terminal not the active window (e.g switch to other window or open Start menu), the lag disappeared.

This problem ONLY occured on Window Terminal, I don't see other application or Windows bundled have this problem.
