yes, but this means you run the soft-3D driver under Xorg, right? That
is known to starve its clients. The stats you sent show no worse than a
few tens of msecs delays caused by CPU scheduling itself:
mrxvt (3730, #threads: 1)
se.wait_max : 18.679129
so the scheduler kept things within the ~40 msecs default latency
target:
.sysctl_sched_latency : 40.000000
