Originally created by @NEXUS2345 on GitHub (Jun 22, 2019).

Environment

Windows build number: 10.0.18632.175
Windows Terminal version (if applicable): 0.2.1715.0 (Windows Store Preview)
NVIDIA drivers version 430.64
NVIDIA GTX 1060 6GB graphics card
Dell Alienware AW3418DW monitor (GSYNC certified)

Steps to reproduce

  1. Connect GSYNC compatible monitor to a computer with an NVIDIA GPU
  2. Enable GSYNC, in either of the available modes
  3. Open Windows Terminal Preview
  4. Scroll mouse around

Expected behaviour

Normal performance without any jittering or lagging as demonstrated in the talks from Build 2019.

Actual behaviour

Significant jitter throughout the entire UI, including other windows, when Terminal is the active window. I attempted to capture it on video, but unfortunately, both direct capture using OBS and my phone camera were unable to capture it.

Additional information

This issue also occurs with the Spotify app, in which disabling hardware acceleration leads to the issue being fixed. I was unable to test this with the Terminal app, as I could not find an option to configure hardware acceleration. I imagine this will be a problem with most variable refresh rate configurations, however, I have been unable to test this as I only have NVIDIA hardware available.
