I have eagerly awaited the ex9dx feature and have tried it out today using the sharedtester patches from a zip file somewhere.
the texture sharing works fine, but after around 13 seconds it stops updating the renderer on the recieving side.
if I delete the renderer and press ctrl+z to get it back, it works again for around 13 seconds.
This happen when I use /allowmultiple and not when I don’t
tty is silent during this
