This issue might be a duplicate of existing issues. Please check:

• math equations not rendered #37326: Math equations not rendered in OpenCode Desktop on Windows 11 (same symptom, same platform, earlier version)

If this is the same underlying issue, please consider adding a +1 or additional context there rather than creating a new report. If you believe your issue is distinct (e.g., it's a regression specific to v1.18.4), please note that in the existing issue.

Same issue. I can confirm that LaTeX math still works in desktop app version 1.17.13 on Windows, but not later versions.

Same issue. Only some of equations are correctly rendered.
