For what it's worth, I discovered that twm and xterm don't trigger the issue, but konsole and other kde things do, which is what led me to discover that setting kern.ipc.shm_use_phys back to default fixed it. This wasn't the case before, I think the last time I updated was about a month ago, May 6. Also, I have these other shared memory related settings in sysctl.conf: kern.ipc.shmmax=67108864 kern.ipc.shmall=32768 kern.ipc.shm_allow_removed=1 I'm wondering if this is an indication that I have/had some bad settings and they finally bit me, or if this is an indication of a bug.
