Hi Bill,
i maintain the Flatpak package, so i can hopefully give some answers.
Flatpak is installing a package inside a sandbox. You don't need a VM to \
test it. It only needs a few system libraries. The advantage is that you \
can run the same package on many different systems. The disadvantage is \
that it brings all libraries it needs (Qt, KDE, etc. in our case), but \
several apps can use this so called runtime environment. I can check on \
Fedora if there are problems due to LabPlot running in the Flatpak sandbox. \
The Z-order or theme problems may also be related to Flatpak settings or \
missing configuration files. We can check this.
best
Stefan
