Cursor / selection offset at end of line - rendered line longer than actual line

[hksae]

Summary

On clean launch (no settings changed) the rendered line looks longer than the real line content. Cursor and selection are offset at end of line.

Steps to Reproduce

1. Open Athas 0.14.2 on Windows 11, 100% scale, default settings
2. Open any file, type 123456789qwerty
3. Click at the very end of the line
4. Press Right Arrow, then select the line with mouse and copy/paste it

Expected Behavior

Click at end puts cursor after y. Selection covers whole visible line.

Actual Behavior

Cursor stops after t, with y rendered after cursor. Right Arrow cannot move further. Selection highlight stops short of visual end, but Copy/Paste gives full correct 123456789qwerty. So model is correct, rendering / hit-testing is offset.

Operating System

Windows
Details: Windows 11, 100% display scale, happens in any file

Version

0.14.2

Thanks for the detailed report! The editor measured character widths before the bundled JetBrains Mono font had finished loading and kept those widths, so the cursor and selection drifted toward the end of each line on Windows. The next release re-measures the font once it has loaded and gives the editor a proper monospace fallback. If you still see an offset after updating, please let us know which editor font and size you use.
