Windows Terminal version

1.19.2682.0

Windows build number

10.0.19045.3448

Other Software

No response

Steps to reproduce

  1. Start WT.
  2. Look at the tab icon.
  3. Open a new tab.
  4. Look at the previous tab icon again.
  5. Switch between tabs a few more times.

Expected Behavior

Pixel-perfect icons everywhere.

Actual Behavior

Only the active tab icon looks good, the inactive one is blurry:

blur

I didn't look into the code, but it could be due to downscaling of inactive tabs by a pixel or so, if the icon gets baked into the tab before this downscaling and not after it:

Oh man I bet this is the 1px gap correction, isn't it.

I wonder how far back this repros. Does repro in 1.18.2681.0. Doesn't seem to repro in WinUI Controls gallery, or File Explorer
