I couldn't reproduce this on Appimage 20.12.3, using the default DejaVu Sans font. Could you please try with this font, and also try a newer version of Kdenlive?

Hello, I tried (with 20.12.3a) and it's still the same, although I do have more info. The pixelation gets worse with the lowering of the monitor resolution, as if there is some kind of blur on the non-roto A but not on the roto A. ALso, It doesn't do it in all the modes. In "write on clear", it looks pixelated, but not on "minimum", so i guess it doesn't really matter since it works fine with minimum.
