Black border around the application window

[savbran]

Hi, I'm wondering why there is the black border around the Byte application window when I use it in KDE desktop environment, like visible into the attached picture.
Is this a bug?

Try to run Byte with this command.

GTK_CSD=1 flatpak run com.github.alainm23.byte

Same problem, but now you can see the error message into the console:

Interesting. I have the same problem with Planner and I think it only happens in KDE, I am installing KDE Neon to be able to find the error more easily. Thanks for your comments.

Hoping you can solve the issue, many thanks. In case you want me to perform some test, please tell me. I can try for example to install some vala package and retry, showing logs... things like that.

Hi Alain, have you any news about this issue?

It seems to be a Flatpak error. I realized that all applications developed with the official elementary OS theme in mind have the same problem.
