flashing lights #19870

@mcandre

Description

@mcandre

Windows Terminal version

1.23.20211.0

Windows build number

1.23.20211.0

Other Software

Docker
zsh

Steps to reproduce

  1. Run docker build... or another ncurses heavy command.

Expected Behavior

The cursor remains visibly steady.

Actual Behavior

The cursor rapidly disappears and reappears as the screen rewrites. If a block cursor is used, then it flickers wildly.

The refresh rate creates a flashing light pattern that I personally find annoying. Curious about the risk of seizures for some developers.

Does Windows Terminal use GPU acceleration like other emulators? I don't have this problem on macOS.

Cursor blink is disabled.
