If I disconnect the touchscreen and connect headless, OpenCPN flatpak works OK.
I will try to get a Raspberry official touchscreen.
What is your touchscreen model?
Could you try disconnecting the monitor and connecting by remote desktop?
I ended up switching back to the deb package and then using the twofing package which seems to work.
The touchscreen is this one, https://amzn.eu/d/7VIBc9G. It's 10.1" with hdmi input, and touchscreen via a usb connection.
Sorry I do not understand this: "I ended up switching back to the deb package and then using the twofing package which seems to work."
I think most of the flatpak errors are permissions issues trying to access host resources (filesystem, graphical environment...). I will do some test using this flatpak app: https://flathub.org/apps/com.github.tchx84.Flatseal
This is a graphical permission manager for any installed flatpak app, try granting full permissions and see if the error persists.
