PDF viewer rendering border around text and objects when creating files with AutoCAD and It looks really bad. Is there a way to switch it off ?

Testfile here:

const encrypt = evaluator.xref.encrypt;
    if (value) {
      if (isRef(this.parent)) {
        const parent = evaluator.xref.fetch(this.parent);
        let parentTransform = null;
        if (encrypt) {
          parentTransform = encrypt.createCipherTransform(
            this.parent.num,
            this.parent.gen
          );
        }
        parent.set("V", name);
        parentBuffer = [`${this.parent.num} ${this.parent.gen} obj\n`];
        writeDict(parent, parentBuffer, parentTransform);
        parentBuffer.push("\nendobj\n");
      } else if (isDict(this.parent)) {
        this.parent.set("V", name);
      }
    }
    dict.set("AS", name);
    dict.set("M", `D:${getModificationDate()}`);
    let originalTransform = null;
    if (encrypt) {
      originalTransform = encrypt.createCipherTransform(
        this.ref.num,
        this.ref.gen
      );
    }
    const buffer = [`${this.ref.num} ${this.ref.gen} obj\n`];
    writeDict(dict, buffer, originalTransform);
