Invert pixel selection displaces

[aenimanu]

Hi everyone;

Not sure if posting in the right folder, but I searched for someone having the same trouble and I didn't find this error:

Whenever I try to make a pixel selection with the lace tool (or any other tool) in Photo, just as quick as I finish selecting, the selection made displaces a bit to the top left corner:

 

It also happens whenever I try to select it and then press comm+⬆︎+I for making the invert selection. This is very unconfortable to work with because I lose all the precision and effort taken in selecting carefully, and I usually have to set it back by hand. I tried this both in Affinity Photo for Mac and Publisher with the Photo Persona, and still having the same trouble.
Note that I also tried unselecting autosnapping, move by whole pixels and force pixel alignment but still doesn't work.
Anyone know what possibly I'm doing wrong or badly set?

Also, If i keep repeating the invert selection, the selection area keeps moving upwards in a progressive scale:

 

 

Thank you all in advance for taking the effort in reading this lines

(EDIT: i'm currently using the latest OS in Mac, Monterrey 12.2.1)

This is a known problem in documents that have a Bleed. Pixel selections displace up and to the left by the Bleed amount. You can work around it by temporarily setting the Bleed value to 0.
