there is a delay in loading images while using a sprite image to show thumbnail images for content.

**Glide Version**:4.9.0

**Integration libraries**:[retrofit2](retrofit:2.3.0)

**Device/Android Version**:Android devices

**Issue details / Repro steps / Use case background**: when loading the images to show as thumbnails in the player like YouTube/ Netflix, when fast forwarding the images are not loading faster. I am using last loaded image as place holder, hence looks like we are showing same thumbnail for longer time. I am also preloading the images to make them render faster. please help me.

**Glide load line / `GlideModule` (if any) / list Adapter code (if any)**:
```java
at the start of fragment since i have a list of images i use the below code
for(int i=0;i
**Layout XML**:
```xml
this is the part of the layout where I use the image view.
......
....
...

```

**Stack trace / LogCat**:
```ruby
No error message
```
