All images in the Featured Servers and Marketplace have a white pixel on the top left

Ever since I started playing Bedrock in 1.15 I noticed how there is a white pixel in all of the images on the Featured Servers tab. This also happens on the Marketplace.

Steps to Reproduce:

1. Go the Featured Servers tab or the Marketplace.
2. Look at the top left of any image.

Observed Results:
The pixel in the top left of the image is white.

Expected Results:
The pixel in the top left of the image is the color it should be.
