Created attachment 141490 [details] Math formula with two sceenshots how it looks like on Win7/10
Created attachment 141492 [details] formula from attachment 141490 [details] opened on Windows 10 with LO 6.1.0 build That is a simple font fallback, looks like your Windows 10 install did not pick up the OpenSymbol font. Verify if it is installed. If not, an uninstall/reinstall should clear when OpenSymbol is present.
Also, the 5.2.7 release is long EOL, please check with current 5.4 release, or even the 6.0 release--you can perform a /a administrative install in parallel to not disrupt you legacy build if it is still needed for some reason.
Thank you very much, the installation of version 5.4.6 solved the problem
