Background image does not display with antialiasingMode = cleartype

[ramsay-vibes]

Environment

Windows build number: [10.0.18363.778]
Windows Terminal version (if applicable): unreleased master 44689b93

Any other software? No

Steps to reproduce

Create a profile with a background image and uses "antialiasingMode": "cleartype" + "useAcrylic": false

This is probably related to #5277, but is this the intended behavior?

Profile used is attached:
settings.zip

Expected behavior

Actual behavior

I realize that #CCC is not a great choice of background color, but just choose it to illustrate the issue.

Wow that looks bad 😦

That should probably not happen, we should probably fall back to grayscale if the user's using a background image, for a bunch of the same reasons as in #5277

This issue just appeared appeared for me with the v0.11.1251.0 release candidate released to the Store today. The previous Store version worked fine with ClearType and a background image.
