Comment # 56 on bug 1205410 from Paul Soto

another issue popped up: worked on some WIFI project last days and sometimes
the touchpad enters another "stupid mode" when I frequently switch the WLAN
BSSID Im connected to. Using Network manager to connect (not wickedd). So after
switching the BSSID about 30 times what happened: 

the mouse pointer suddenly becomes very slow (about 1/3 of the original speed)
and feels like it has no acceleration at all. No error message or anything in
the kernel log, just happens. So far I experienced this 3 times - now the
project is done so Im not switching the BSSID anymore (at least not 30 times in
a row).

Could not diagnose it what actually happens - hey guys I also have to work on
something and not debugging this god damn laptop and OS.

What fixed the latest issue: lock the screen and put the laptop to sleep for a
couple of seconds (5s) then wake it up again, enter the password for screenlock
and it works again (mouse back to normal behavior).

The mouse however feels different from the first bug (when it enters another
crazy mode with the jumpy two finger scrolling) - absolutely not the same.
