How to fix image reprocessing?

here is such a task

gulp.task('img-responsive-1x', async function() {
  return gulp.src('app/img/**/*.{png,jpg,jpeg,webp,raw}')
    .pipe(newer('app/img/@1x'))
    .pipe(responsive({
      '**/*': { width: '50%', quality: quality }
    })).on('error', function (e) { console.log(e) })
    .pipe(rename(function (path) {path.extname = path.extname.replace('jpeg', 'jpg')}))
    .pipe(gulp.dest('app/img/@1x'))
});
// Produce @2x images
gulp.task('img-responsive-2x', async function() {
  return gulp.src('app/img/**/*.{png,jpg,jpeg,webp,raw}')
    .pipe(newer('app/img/@2x'))
    .pipe(responsive({
      '**/*': { width: '100%', quality: quality }
    })).on('error', function (e) { console.log(e) })
    .pipe(rename(function (path) {path.extname = path.extname.replace('jpeg', 'jpg')}))
    .pipe(gulp.dest('app/img/@2x'))
});
gulp.task('img', gulp.series('img-responsive-1x', 'img-responsive-2x', bsReload));
