Public bug reported: This happened soon after logging in. The entire desktop (mouse cursor included) would freeze for maybe 30 seconds at a time. The activities screen seemed to trigger it. The dock appeared empty.
After a few minutes of this I rebooted and things seem to be alright now. Relevant log messages start on May 5 at 11:10 AM US/Eastern time. Similar messages appear on March 31st. I don't recall whether I experienced similar freezing behavior at that time.
