Scrot doesn't capture VLC fullscreen

[desmphil]

Hi,

Im using scrot over a small flask web site to monitor what is (playing) on the hdmi display.
This works fine with Chromium, or other any application running.

As soon as I start a VLC video fullscreen in display=0, then the scrot capture only return black images.
If i start VLC without the --fullscreen option, the capture works.
Any idea?

scrot command line
sudo -u pi DISPLAY=:0 scrot --overwrite -t 5 -z

vlc command line
vlc --fullscreen --no-qt-privacy-ask --no-osd --loop --random --no-audio /home/pi/Videos/video1.mp4

Seems to work okay with mpv's fullscreen, I don't have vlc installed. Please provide some more information about your setup as well:

1. Which scrot version?
2. Which WM are you using?
3. Is a compositor involved or not?

Also try to see if you can reproduce it with mpv or if it's just vlc that's causing issue.

scrot version 1.5
running on Raspberry PI 4
Latest version

PRETTY_NAME="Raspbian GNU/Linux 11 (bullseye)"
NAME="Raspbian GNU/Linux"
VERSION_ID="11"

VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye

So i tried with MPV and the screencapture works very well.
mpv --profile=myprofile1 /home/pi/Videos/video1.mp4

Profile:
[myprofile1] #A simple profile, top level area ends here
profile-desc="a profile" #Optional description for profile
fs=yes #Start in full screen

Has this been fixed? I'm encountering similar issues with a steam game in full screen. Weirdly enough this didn't happen until I switched to using an external Nvidia GPU. For reference I use bspwm with no compositors.
