Thanks, that workaround does mostly work. However, the window controls
still don't look quite right even after disabling and enabling the
minimize and maximize buttons in Gnome Tweaks.

Title:
dconf overrides are not read by flatpaks on wayland sessions
Status in flatpak package in Ubuntu:
Invalid
Status in xdg-desktop-portal package in Ubuntu:
Confirmed
Bug description:
"dconf supports distros installing override files into the system,
then when queried dconf will look at user setting, then fallback to
distro setting, then fallback to default setting. In a sandbox we can
ask dconf for the user setting but we don't have disk access to the
override files"
So what this means is that on wayland flatpaks can't read the default
overrides from the session (eg Ubuntu choosing Ambiance and Minimise,
Maximise, Close etc) as it doesn't have permission to read the system
files only user ones. (this doesn't affect X11 sessions as gtk reads
from xsettings instead).
This will be solved when the settings portal [0] is used in xdg-
desktop-portal, as that runs on the host outside of the sandbox it is
able to read the necessary files.
# Workaround
Install gnome-tweaks, change your theme to something else and then
back to Ambiance. Also for the window controls change one of them from
true to false to true. This will then write user settings to dconf
which the flatpak's can then read.

=== Original Description ===
System: Ubuntu 18.04.1
Flatpak version: 1.0.6-flatpak1~bionic (from
https://launchpad.net/~alexlarsson/+archive/ubuntu/flatpak)
Description: Flatpaks using GTK3 default to the Adwaita theme in a
Wayland Gnome session. In Xorg sesions they are themed correctly. The
attached screenshots demonstrate the same version of Gnome Builder
running in Communitheme-Wayland and Communitheme-Xorg. However,
flatpaks that use Qt5 (like KeepassXC) seem to be themed correctly
under Wayland.
