Jittery desktop mode.
In Debian 10, since an update a few weeks back, the display has
included a weird spontaneous jittery mode. The browser can work
for several minutes with no problem. Then with no warning
components in the desktop begin flashing. A desktop chooser or
indicator in the center of the screen rapidly cycles 0, 1, 2, 3, 0, ...
It seems to be triggered by a mouse click; haven't found anything
more specific. If keyboard and mouse input are suspended for
several seconds the activity dies down. When the episode is
finished, seemingly normal usage can continue.
A few seconds of the behavior is visible here.

Wayland/westan is also installed. In weston the mouse pointer
can jump erratically but other graphical components are stable.
At present I wouldn't know what to file a bug report against.
Ideas?
Thanks, ... P.
