No. Apply a little engineering to this instead of running around acting
on random unexplained proposals people don't agree works. Right now you
look like a politician - mindlessly squawking about things you've not
tried and proposing anything and everything which might improve matters
without working out if they would and why.

The tty layer is getting improved and fixed by applying proper
engineering methods not by random flapping.

So:

observe, and if need be experiment to get further data
produce a model of the behaviour which explains the data
make the changes the explanation requires
test

No they provided relevant data or enough info I can reproduce it here.
