 Summary of the bug: When I capture digital clock in the systray on Ubuntu
 20.04 Mate Desktop, the video from the captured area looks erroneous,
 clock in the video sometimes repeats between a few seconds back and forth,
 sometimes it captures a still frame from the previous capture. It happens
 especially in the systray digital clock. When I capture the whole screen
 it records rest of the screen
 but systray digital clock still behaves erratic.
 How to reproduce:
