Describe the bug
I have updated several 2,2"Solum tags (ST-GR22080) to the latest fw 41 0x29
After the first update, I noticed that the default "AP found at...." screen was not properly scaled.
It looks like it is been presented for a bigger display (e.g. 2.9")

To Reproduce
Steps to reproduce the behavior:
Update a 2.2 tag to firmware 41 0x29

Expected behavior
I would expect the data to show correctly and be able to read the full text.

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context
However, there is not a very big problem, because when any data is written to the tag, it get's presented as expected, only when default information shown (default bootup, AP found, deep sleep) the scaling is incorrect
