Hiya Martin,
Thanks for messaging over your feedback! We really appreciate it.
Due to the size recommendation being set by Twitch as "best practice for the best quality on your channel", the pixel count is quite low and therefore if you zoom in a lot when you are editing - you will see the pixels. This would not be the case on your channel as they are purpose built for the highest quality size limits.
If it is something outside this, please can you email some screenshots to orders@getrektlabs.com so we can check it out.
Thanks!
