Thanks for doing that, so at least the commit is very related to
screenpad's. Now the commit was backported to not only 9.12.91 but as
well 7.0.10 (from 7.1-rc1). Can you confirm if the issue is as well
present with the kernel in testing and/or unstable (aka 7.0.13-1 or
7.1.3-1)?

If the issue is present there as well then it's generic regression
otherwise something might be missing in the 6.12.y series, in both
cases we can report the issue upstream. But clarifying if 7.0.13 and
in particular 7.1.3 is affected as well would be very helpful.

Can you please test those?

Regards,
Salvatore
