Partial screenshot functions won't capture GTK apps

[ghost]

Hey, I just came across your script via r/unixporn. Nice one.

I'm having an issue with partial screenshots though. It only occurs when trying to capture GTK applications windows.

When clicking on a GTK app window, It'll just capture a pixel, which seems to be the same color than my window border color (I'm using bspwm). No issue with Qt apps or my terminal windows (kitty).

I guess the culprit is either ffcast or slop because replacing

crtc() {
[...]
  ffcast -q $(slop -n -f '-g %g ') png /tmp/screenshot_clip.png
[...]
}

crtf() {
[...]
  ffcast -q $(slop -n -f '-g %g ') png "$screenshot_directory/$dt.png"
[...]
}

with

rtc() {
[...]
  maim -s -u -m 10 /tmp/screenshot_clip.png
[...]
}

crtf() {
[...]
  maim -s -u -m 10 "$screenshot_directory/$dt.png"
[...]
}

solves the issue.

Maybe it can be fixed without having to install maim, I don't know.

Cheers

Haha that's funny - I saw the title in my email earlier and thought "hmm I 'll probably just replace those bits with maim then.." but it looks like you beat me to it 😁

I actually just checked while writing this and it works for me when grabbing Nemo on AwesomeWM in Arch. I think Maim uses Slop under the hood so it might be ffcast causing the issue..

Anyway, since I can't recreate I'll just leave this as a workaround for people with the issue rather than add another dependency for everyone.

Thanks for raising :)
