I’m using Julia 1.9.4 binaries from AUR (en) - julia-bin
GR version v0.72.10
WebIO version v0.8.21
Mux version v1.0.1
Trying to make an interactif plot following the Mux example here: How to make dynamic plots with slider bars - #4 by ericphanson
Everything succeeds but when I open the browser window I get the plot, but not interactive since the websocket connection seems to be broken. I get this error in the terminal (pretty long, but I think the relevant info is at the beginning):

The error seems to come from gksqt, but when searching “gksqt”, I’m mostly seeing Julia+GR related issues and no clue how to fix this.
I’m opening this thread to get help to better understand the problem and maybe fix it ^^
