Hello,
Over the past few weeks, I've noticed the following behavior on several computers:
approximately every 1-2 minutes, the screen of their computer goes black for 1 second and then the display comes back.
This started when I deployed the Jamf PaperCut Print Deploy Client on the computers.
Having a machine with the problem on hand, I scanned the system logs and every time the screen went black, I had this in the logs:
jamfRemoteAssist[15726] triggered unnest of range 0x7ff85c600000->0x7ff85c800000 of DYLD shared region in VM map 0xc3e4dd3aacf1a315. While not abnormal for debuggers, this increases system memory footprint until the target exits.
system.log
However, Jamf Remote Assist was activated at the end of November and the problem appeared in mid-December (PaperCut deployment). I then deactivated Jamf Remote Assist (Settings -> Computer Management -> Security). 15 minutes later, the machine took note of the change:
Checking for policies triggered by "recurring check-in" for user "j.reynaud"...
The management framework will be enforced as soon as all policies are done executing.

No patch policies were found.

And since then, no more black screen and this in system log :

Has anyone else had this problem?
The computers have macOS Monterey.
