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
