No, I had hinting problems with my working (normal) system (MX-23) in some wine programmes. Only in Wine programmes.
Sorry for confusion.
My idea was, that the culprit could be freetype. My idea was to replace the freetype version through an other freetype version, because in MX-19 I had not this problem and there I used an other freetype version, of course.
As I did not know, if the replacement is possible, I have tried this not in my normal system, because I did not want to destroy anything. This is why I tried the freetype replacing in a VM. This was the only reason, why I made this in a VM in post #1.
I didn't describe the background of my motivation in post #1 to keep it simple.
