I don’t see how hinting issues can cause this degree of character misplacement. This looks more like, say, a glyph cache bug.
I had no problem reproducing this with the software pipeline. When I force the GPU I get much better results (prism.forceGPU=true). In both cases the text is a little on the fuzzy side but the es2 pipeline is placing the glyphs correctly. > On Aug 4, 2024, at 9:09 PM, quizynox <quizy...@gmail.com> wrote: > > Hello, > > Thanks for the answer.
