Some time in the last few days Flameshot broke so that when I tell it
to take a screenshot it only lets me select the region I want from one
of my two monitors. It used to correctly do both monitors.
When I tell it take the screenshot, both monitors flash as if it is
taking a picture of both of them -- I suspect it's actually GNOME
that's doing the flashing -- but then I can only select from my
primary monitor.
Note that my two monitors are connected via DisplayLink, but given
that this worked as of a few days ago and stopped working I'm not sure
this is relevant.
An unfortunate regression!
