Originally created by @rolflobker on GitHub (Feb 6, 2021).

Microsoft Windows NT 10.0.19042.0
Windows Terminal Preview Version: 1.6.10272.0

Steps to reproduce

Open a new tab, with following profile;

  {
    "guid": "{a232ec02-ced9-4160-a72d-16cbc00786c6}",
    "name": "SomeServer",
    "commandline": "c:/profile/someserver.cmd",
    "tabTitle": "SomeServer",
    "backgroundImage": "C:/profile/backdrops/somebackground.jpg",
    "backgroundImageStretchMode": "uniformToFill",
    "backgroundImageOpacity": 0.5,
    "closeOnExit": "always",
    "bellStyle": "none",
    "fontWeight": "light",
    "colorScheme": "Solarized Dark Higher Contrast"
  },

c:/profile/someserver.cmd contains;

set display=localhost:0.0
ssh -Y -C -c aes128-ctr myserver

And myserver is ofc configured in .~/ssh/config as follows

Host *
ForwardAgent yes
ForwardX11 yes
ForwardX11Trusted yes
IdentityFile ~/.ssh/mykey
ServerAliveInterval 60
ServerAliveCountMax 2
User myusername

Host myserver
Hostname
LocalForward 3306 localhost:3306
IdentityFile ~/.ssh/otherkey

Expected behavior

Open the session without popups, being notified about missing shaders,
And WT remaining active. I noticed it sometimes completely dissappears, but have not been able to pinpoint exactly if that coincides with the "Unable to find the provided shader ""." message

Actual behavior

Almost always pops up saying "Warning: Unable to find the provided shader ""."

Below animation shows me opening several tabs with pwsh, powershell, cmd
Before opening the sshserver.cmd profile.
I made a copy of the profile pointing to a different background image, this did not change the behaviour

At the end, we see 1 succesful open, then an open with warning message, then another open with warning message before WT just complete closes (all gone)
