Here is some more info:
I loaded the module with option core_debug=15.
When I run with low CPU load (vx driver), I get the following log lines:

Very regular, just one "first active".
With high CPU load (x11 driver) I get:

Strongly irregular, many "first active", sometimes two "field counts" after
each other.
Hope this helps.
