Font rendering becomes jagged / aliased after VS Code 1.107.1 on Linux

[SphenHe]

Type: Bug

Steps to Reproduce:

1. Install VS Code 1.107.0-1765353617.el8 or any later stable version on EL8-based Linux
2. Open any text file (e.g. source code, Markdown)
3. Observe font rendering quality in the editor

Changing fonts(editor.fontFamily) does not resolve the issue, and the same behavior is present in the latest Insiders build.

Possible duplicated of #260391

Everything worked fine in v106, but this issue arose in v107. So the rendering problems may have been caused by changes made between v106 and v107 (but not between v102 and v103)?

[danielrouco]

The issue was reopen because the solution that they used to fix it in v103 is no longer avaliable on Chromium now

Reopening now that we are on runtime version Chromium 142 which doesn't support disabling fontations stack on linux.

Can confirm, editor font looks blurry on the latest version. (Non-bitmap, JetBrains Mono though the default one isn't any better)

Font rendering is now totally botched on Windows too:

(image scaled up 2x for clarity)

what on earth is going on with that underscore 😿

[mindplay-dk]

This appears to be a passing issue somehow? I tried changing the "Editor: Font Family" setting to just monospace, and it rendered perfectly... changed it back again to the previous setting Consolas, 'Courier New', monospace and now for some reason that renders correctly too... very strange. 🤔

Can confirm I also have this issue, on Linux moving from 1.106 to 1.107 or 1.108. Fiddling with "Editor: Font Family" doesn't fix it for me. I have rolled-back to 1.106 using the deb for now.

[mindplay-dk]

I managed to catch it in the act - this is what I'm seeing on Windows 11 and how I "fix" it:

I don't know what causes the blurry fonts, but when it happens in the console, I can "fix" it by resizing the view.

Could this be something trivial like a CSS rounding error of some sort?

Perhaps a size of something somewhere in the UI that isn't being rounded before it's applied to style properties?

1.109.0 has the same issue. Rolling back to 1.106.3

Any ETA on this? A large number of Linux users are forced to stay on version 1.106.3
