In python as example I get:

EDIT: restarting the machine (not the WSL but the entire machine) I get the command xeyes working one time only. From the second exectution the error appears again

grufoony@Grufoony:~$ xeyes
grufoony@Grufoony:~$ xeyes
Error: Can't open display: :0
grufoony@Grufoony:~$

EDIT2: it seems to work more than one time (also restarting wsl) but for a limited amount time... it seems pretty random at the moment

Thank you for reporting this @Grufoony. I wonder if there's an issue with X. Could you share the output of echo $DISPLAY when you see that error ?

[Grufoony]

Here it is:

grufoony@Grufoony:~$ echo $DISPLAY
:0

Ok thank you, this looks correct. Transferring to wslg to investigate further
