Differerence in rendering result for UseGdiPlusTextRendering

I am experiencing a strange issue. I use font Cinzel [https://dafont.com/cinzel.font](url)
There is a weird issue with spaces between some words (not everytime for every text)
This is how this text
`lltast test`
looks in GDI+ rendering

and with non-GDI+ rendering

Any ideas why?
Thank you very much

Start with the UseGdiPlusTextRendering option and reproduce the reported Cinzel example in both GDI+ and non-GDI+ modes. Compare the rendered spacing for the supplied text and determine whether the difference is reproducible; done means the cause is identified and the two rendering results are corrected or the limitation is documented.
