strange problem with image rendering

I noticed a strange problem with image rendering. For example here: https://pngtree.com/free-powerpoint-background/12 some of the images do not show up. Screenshot_20210806_161600

But in chrome. Screenshot_20210806_161656

The Trello icon is highlighted in red https://trello.com/ Screenshot_20210806_161820-2

And this is an example of QR code generation in profile on https://readdle.me Screenshot_20210806_161855

If you refresh the page you'll see a normal QR code for a moment, but it immediately turns into this mess.
