Davide, > The new output is much worse, most of chars have single dots protruding in the external outline.
We won't be able to help you unless you help us to reproduce or see the issue. At the very least you should name the font and the size, and give a screenshot. Also, in our mind, only bugs in 2.12.1 are worth fixing. You should try this most recent version in case it is fixed already. There could be other software that disabled the hinting too. Therefore, we prefer that you show the issue using freetype demos like ftview or ftgrid. Does this make sense? Your report does not have any details. You can use https://gitlab.freedesktop.org/freetype/freetype/-/issues once you have mode details. Can you help us to help you? Alexei
