About using custom DownSampleStrategy

[WSWSKIM]

Glide Version: #4.12.0

Device/Android Version:
Android Tiramisu

Issue details / Repro steps / Use case background:
I am using custom DownSampleStrategy (extends DownSampleStrategy).
When I put the new constructor in downsample() as shown in code 1 attached below,
A flickering phenomenon occurs when the change of images is notify.(RecyclerView)

If I use a static variable like number 2, there is no issue.

Do you know why,
For example, does it take a lot of memory or time to create a new DownSampleStrategy?

The code:
1. using new constructor

RequestOptions options = new RequestOptions().error(R.drawable.error_image);
options = options.downsample(new CustomDownSampleStrategy()).optionalTransform(new CenterCrop());

Glide.with(context)
.load(url)
.apply(options)
.into(imageView);

2. using static variable

private static final CustomDownSampleStrategy CUSTOM_STRATEGY = new CustomDownSampleStrategy();

RequestOptions options = new RequestOptions().error(R.drawable.error_image);
options = options.downsample(CUSTOM_STRATEGY).optionalTransform(new CenterCrop());

Glide.with(context)
.load(url)
.apply(options)
.into(imageView);
