Description

I am getting an error when using `:qt5` backend on linux RHEL 8.8

```
using PyCall
pygui(:qt5)
using PyPlot
fig,ax=subplots()
```

gives this error

"Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed"

Other backends work ok. However I get a weird error when using `:tk` backend with the `ImageView` package.
