X Window System error on Trisquel (Ubuntu 22.04 LTS)

[Caleb Herbert]

Hi Flatpak,

I'm having trouble running some Flatpak apps on Trisquel 11 (Ubuntu 
22.04 LTS) and have not been able to find a solution by searching online 
for the error message.

The error:

caleb at hermes:~$ flatpak run org.gnome.Builder

(gnome-builder:2): Gdk-WARNING **: 14:59:14.270: The program 
'gnome-builder' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRegion (invalid Region parameter)'.
   (Details: serial 915 error_code 140 request_code 138 (XFIXES) 
minor_code 11)
   (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.)
caleb at hermes:~$

Apps that run fine:

* Signal
* Zoom
* Dino
* Impression
* Popsicle
* FreeTube
