Here are a few screenshots showing the processes using the highest CPU. All other processes were below 5%.
At the time, overall CPU utilisation was around 30%, and everything on the built-in display felt responsive and snappy. Memory usage was also within normal limits, with no pressure or indication of a leak.
However, the DisplayLink-connected monitors were extremely laggy and effectively unusable.
When I initially installed 15.1, everything worked normally for approximately 30+ minutes. The lag then started without any change in workload or applications in use. What’s particularly strange is that after rebooting, the laggy behaviour was present immediately.
My first thought was a potential memory leak, but a reboot should at least temporarily resolve that, which doesn’t appear to be the case.
I reverted back to 14.2 and observed similar CPU and memory metrics in Activity Monitor, but without any DisplayLink lag.
At a stretch I guess it may be related to Microsoft Teams — are there any known compatibility or performance issues between Teams and macOS 15.1?
