Problems on ubuntu mate 24.04

Hi,
any ideas about my new problems on ubuntu mate 24.04.
See also my bug reports:

The origin project seems to be dead - isn't it?

I have rebuild the origin and your version:

sudo apt install build-essential
sudo apt install devscripts bzr
sudo apt purge onboard onboard-common 

bzr branch lp:onboard
cd onboard
fakeroot debian/rules clean
fakeroot debian/rules build
export DEB_HOST_ARCH=amd64; fakeroot debian/rules binary
cd ..
sudo dpkg -i onboard_1.4.1+rev-0local0_amd64.deb 
sudo dpkg -i onboard-common_1.4.1+rev-0local0_all.deb 
sudo dpkg -i onboard-data_1.4.1+rev-0local0_all.deb

but always

onboard -d warning
(onboard:3071): Gdk-CRITICAL **: 22:29:31.659: gdk_window_thaw_toplevel_updates: assertion 'window->update_and_descendants_freeze_count > 0' failed
Segmentation fault (core dumped)

after the first click

I think the origin onboard project should be cleaned up and simplified for an ongoing usable project fork.
I could contribute to keep it alive...
