Overlay html , render font not correct (cross platform)?

When show html on google chrome (Mac OS)—> it’s ok
but when render (overlay HTML) by shotcut —> the font is not same html of browser . (bug: letter spacing, character not same 100% html of browser)

How to fix for cross platform ? I only use a TTF file
plz help, thanks

The web runtime between your desktop browser and the one in Shotcut are different. You are not going to get exactly the same results. You need to learn to live with that.
