Can't reproduce on Ubuntu 20.04 LTS.

Right, i have tried again and i can do smaller screengrabs into the clipboard.
As soon as the area grabbed is getting bigger the clipboard remains empty.
I'll try to figure out the exact size i can do successfully.

update:
My apologies, i made a mistake using gimp.
Pasting a small image worked instantly, but when i wanted to paste a larger one (my desktop is triple screen) it didn't work. Apparently you first have to create a new picture large enough to hold it.
Using gnome-screenshot this was not necessary, i could immediately paste the whole desktop into a blank gimp-session.

Yes, it's not work for mate-1.24.0. More. If opened context menu, screenshot area not working. Fix it. Pls.

I have the same problem in Debian bullseye.
It only seems to happen when I pass on commands. Ex:

mate-screenshot -a -c
mate-screenshot -w -c
mate-screenshot -c

If I use mate-screenshot -i and click my way into copying, then the program works just fine. Perhaps the buttons use a slightly different code?

[adefaria]

The man page for mate-screenshot lacks any kind of description for -c.

[igutermes]

@adefaria is correct. -c will only be mentioned in the summary of the --help option (see here for a peek), but is not described in the man page.

Though the problem os copying is persistent, I have had some success in applying this workaround. I have been testing for a while now and so far so good. What does the trick is the sleep part.
Just create an executable and link it in mate-keybinding-properties, works well.

Mate version 1.26.0.

Yes, I implemented a script to suit my needs using that concept. I added in a zenity popup to save the captured area to a file. Some apps (slack, thunderbird) allow you to simply paste an image from the clipboard and other apps (voice.google.com) need a file. So I prompt to save the file and if I intend to use the image in something like voice.google.com then I'll save the file, otherwise, I don't bother. The popup times out not saving the image to a file. Also grabbed a sound of a camera click to play it to emulate taking a "screenshot".

#!/bin/bash
timeout=10
screenshot_directory=/tmp

function yesno {
  question=$1
  
  zenity --question --text "$question" --width=300 --timeout=$timeout 2> /dev/null
}

mate-screenshot -ac
aplay ~/Conf/CameraClick.wav

file="$screenshot_directory/$(date +%F@%T).png"

if yesno "Save screenshot as $file?"; then
  xclip -selection clipboard -t image/png -o > $file
fi
