[Question] Map size different to Valetudo-Mapper Hassio-Addon and "normal" Docker

[thundergreen]

Describe the bug

When i install Valetudo Mapper via docker (not Hassio-Addon) my Map is small than the Hassio addon
How to Reproduce

Steps to reproduce the behavior:

1. start docker container with config file (I use docker-compose.yaml)
2. camera is added to Home-Assistant but smaller
3. Both site codes (Lovelace) are identical!

Expected behavior

Both camera Images should be the same size
