@nytpu That's the guide I followed as well. The flickering is really bad for me to the point I can't work with the software in this state. I think it's exacerbated by me having to bump up the UI DPI to 192 in order to make it work with my 4K displays.
Apart from these two issues, there's also paths outlines not matching their actual shape. It's listed under known issues.
