I knew, I read the PR because I was interested who took the pity on this long 
standing disadvanted compared to some othe operating system... So you alredy 
got my thanks in mind :)

Hmm, if I don't use -A (dynamic acc) the problem still persists, the linear 
acceleration is droping info, hence the culprit. I don't have a problem with 
dynamic acceleration when the linear is disabled, so it can't be a regression 
by your patch I think.

Thanks,
