Fix ANR & Crash on Ryu

Fixes impossible dequeue crash as the wrong
start point of the frame was used. We need
to use the start point for RT, not the start
point for the frame.

Workaround for sysui ANR caused by what appears
to be a driver bug. Drivers with the bug
will have transiently higher memory usage.
Drivers without the bug will be unaffected.
