Edit: this patch has been merged into OpenBoard 1.6.4, so this issue is closed.
These days I'm forced again to do lessons from remote. My school asked me to refer to
Google Meet for the videoconferences and one thing I disliked was the
Jam interactive whiteboard, which is completely inadequate for scientific subjects. On the other hand OpenBoard, my favourite board tool that I successfully use with
Zoom, seemed not to be recognized as an application to be shared, because it runs fullscreen.
After some googleing I found a patch from this guy (I big thank for his work!) which forces OpenBoard to run in a window, but at the cost of passing a variable at compilation time. I modified the logic of that patch so that a user can set how OpenBoard will run just by modifying an option in the config file. The "run windowed" feature is disabled by default, so it will not bother those teachers who are already familiar with the interface, but it can be easily switched on by advanced users.
To get OpenBoard running in a window just switch this option to
true in the /opt/openboard/etc/OpenBoard.config file
Each user can do the same by overriding this setting in his/her personal ~/.local/share/OpenBoard/OpenBoardUser.config file.
The following prerequisites must be already installed:
libpaper libass x264 libfdk-aac ffmpeg quazip-qt5 qt5-webkit. My patch is for the

You may want to reproduce these steps when building the package for your specific distro.
