Fix scaling on Linux

[EtaleMorphism]

I'm using the Flatpak of version 1.2.63.394.g126b0d89 of the Linux Spotify client. I have a 4K monitor and so rely on scaling for things to look good. I have the Scale setting in GNOME set to 125%.

Scaling does not work reliably in the Linux Spotify client. The first time I start it, it looks like scaling is not applied, and so everything looks very small. If I restart it, it picks up the correct scaling and things look how they should.

I am aware there are workarounds to this issue, but I would like it to be actually fixed. I don't have this issue with any other software, including other Flatpaks. It looks like there have been issues with scaling in the Linux version going back to 2016.

Did you enable Wayland support for your Flatpak installation? You can use e.g. Flatseal to enable the Wayland socket. You can check out Spotify's Flatpak repository README, too.

I've just tested going between 125, 150 and 200% scaling on KDE Plasma and it behaves correctly. I know that it wasn't the case when the app was running via XWayland 🙂
