failed to run then started working

The desktop integration shortcut failed to open Flatseal flatpak, so I tried to run it interactively inside tmux and got this error.

❯ flatpak run com.github.tchx84.Flatseal
libEGL warning: DRI3: Screen seems not DRI3 capable

(com.github.tchx84.Flatseal:2): Gdk-WARNING **: 13:44:03.254: The program 'com.github.tchx84.Flatseal' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 1917 error_code 8 request_code 149 (unknown) minor_code 4)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Suspecting that problem could be related to running inside a terminal multiplexer like tmux, I was able to work around by running it without tmux:

gnome-terminal -- flatpak run com.github.tchx84.Flatseal

After running it once this way, now I can open it normally with desktop integration.

I'm unsure what the original problem was.

@qrkourier thanks for sharing this report, I am honestly unsure as well... could you:

1. Describe your environment, e.g., OS version, flatpak version, etc.
2. Is this reproducible with another GTK4 application? e.g., say Decibels.
3. If reproducible, describe the exact steps.

I didn't encounter this issue with Decibels. It's no longer reproducible but it was until I ran it once outside of tmux.
