Flatpaked apps doesn't start under wayland, if called from another app

[Ben Aceler]

I run Gnome Wayland session and I have several apps installed from flatpak - gthumb and evince are among them.

If I download a file using a web-browser and try to open this file from the browser's "download" menu, the PDF or JPG files won't open. I can fix it by setting up evince or gthumb to run x11 by disabling wayland with flatseal.

Web-browser is not installed by a flatpak or snap, so it can be vivaldi or yandex-browser.
