New description:
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.
Edit: I noticed that it happens with compiz window manager. I tried
metacity, it records the clock well.
Edit2: It also fails to capture the digital clock properly in Gala,
Mutter, GnomeShell window managers.
