i don't know if issue is unique to my machine /my configuration is
bordering on being frankendebian/ or more wide
as usual i tried to update my machine, and on `sudo apt full-upgrade`
saw this:
```

as i understand, lib packages in stable-backports has been updated to
26.* version, while mesa drivers are still 25.* - and since full-upgrade
ignores automatic/manual flags on these packages and may even remove
some packages - it suggest removing drivers, while upgrading library files
```

```
did i bork my system with apt tweaking/pinning or is it issue with
debian trixie-backports repository?
