Steps to reproduce

1 ) Open an instance of Windows Terminal
2 ) Enable transparency on the display profile
3 ) Initiate a Teams call
4 ) Initiate whole screen sharing on an external monitor (laptops)

Expected Behavior

The ability to interact with applications and have the mouse respond normally

Actual Behavior

Mouse tracking becomes jittery and sluggish, and applications take tens of seconds to respond to basic input; Windows Terminal, which is on a non-shared display, goes into a not responding state.

Are you using an Nvidia GPU and a variable refresh rate display? If so, you're unfortunately subject to this bug: #649

I've two adapters, an Intel 630 and an Nvidia Geforce GTX 1050.

What about the variable refresh rate display? Do you use one (either G-Sync or FreeSync)?

[msherian]

No the displays I am using are pretty basic: https://www.philips.ie/c-p/278B1_00/monitor-lcd-monitor-with-powersensor and the on-board XPS 9570 LCD panel. I don't even have the G-Sync option in my nVidia control panel

Unfortunately I've never seen this issue happen on my end (and as far as I'm aware no one else on the team had this happen to them). Could you try these two things?

• winget shows the version that they provide, not what is actually installed. To get and check the version please follow these steps:
  • Open the About dialog:
  • Check that you use version 1.17.12191.0.¹
    If it's older than that, please open the Microsoft Store app, navigate to your Library in the bottom left corner and update your apps. It should then install 1.17.12191.0.
• Enable AtlasEngine in the Rendering settings:
