Please tell us which apps are affected.

Please also help us to identify the cause by opening two Terminal windows. In the first window please run 'top' so you can see high CPU users. In the second window please run 'journalctl -f' so you can see new log messages. Now reproduce the bug again and tell us what you see in those terminal windows while the bug is happening.
