After updating Miktex 2.9, preview_math does not work. It works only in simple cases.

Same problem on TeXLive2018, openSUSE TW. I believe this is related to the Ghostscript that was recently updated to v. 9.25. As far as I can tell, GS fails to convert the temporary .pdf to the .png. The latter appears to be of zero length. The simplest formulas are converted nonetheless. Same problem with image previews, by the way.

I just solved the problem. I have set the "preview_math_hires" to false in the settings of latextools: "preview_math_hires": false, It works.

"preview_math_hires": false, It works.

I confirm this fixes the issue with math previews. The figure previews still give errors for me, like 'failed to create preview thumbnail'.

"preview_math_hires": false, It works.

Worked for me too. Thanks!

After a recent system update, "preview_math_hires": true again works for me. However, a similar problem with figures preview still persists. A hover on a figure results in an Error: failed to create a preview thumbnail. Ghostscript is 9.26a-1.2.x86_64 on openSUSE TW.

Btw, may I ask if the development of the package is stalled, or is it just the work is being done behind the scenes? Thank you anyway.

@JackGin I can only speak for myself: We started to create "version 4" on a separate branch, which removes ST2 compatibility, includes a lot refactoring, and adds nice features. However unfortunately the development slowed down/stalled due to a lack of time/motivation/other priorities and it wasn't released yet (I still want to release it). You can use the prerelease to install that version.

This is still an issue, and just started happening to me recently.

"preview_math_hires": false fixes the issue. Unlike others, I do not have an issue with the figures.
