Describe the bug

Bug Description

Korean text appears as separated jamo (individual Hangul components) in Warp Drive document viewer on Fedora 42, while displaying correctly in the terminal portion and shell operations. Interestingly, the same setup works perfectly on Debian, suggesting this is a Fedora-specific issue.

Environment

• OS: Fedora Linux 42
• Warp Version: v0.2025.06.04.08.11.stable_03
• Desktop Environment: GNOME
• Display Server: Wayland
• Terminal Font: Noto Sans Mono CJK KR (properly configured)

Expected vs Actual Behavior

• Expected: Korean text displays as complete characters (e.g., 여기)
• Actual: Korean text displays as separated jamo (e.g., ㅇㅕㄱㅣ)

Where the issue occurs

• Warp Drive document viewer: Korean text broken (jamo separation)
• Terminal area: Korean text displays correctly
• Shell operations: Korean input/output works perfectly
• Copy/paste from Drive: Korean text is correct when pasted elsewhere

Distribution Comparison

This appears to be a Fedora-specific issue:

• Fedora 42 + GNOME + Wayland: Korean jamo separation issue in Warp Drive
• Debian: Korean text displays correctly in Warp Drive with same setup

Font Configuration Status

Korean fonts are properly installed and configured:

The issue you are experiencing—Korean text displaying as separated jamo in the Warp Drive document viewer on Fedora 42, but not on Debian—is consistent with known Unicode normalization and font rendering problems in Warp. This is a recognized, platform-dependent issue, but there is no definitive solution or workaround at this time.

To anyone else facing this issue, please add a 👍 to the original post at the top or comment with your details, and subscribe if you'd like to be notified.

As a workaround, you can disable google-droid-sans-fonts altogether.

Adding the following configuration to ~/.config/fontconfig/fonts.conf fixed the issue in Fedora 42:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "urn:fontconfig:fonts.dtd">
<fontconfig>
  <rejectfont>
    <glob>/usr/share/fonts/google-droid-sans-fonts/*</glob>
  </rejectfont>
</fontconfig>
