I installed ParaView-5.8.0-MPI-Linux-Python3.7-64bit.

Running the command  
`paraview-mesa paraview --backend llvmpipe`

results in the error message:  
`Xlib: extension "MIT-SHM" missing on display "XXX:X".`

and a broken Render View:

The Linux distribution is Red Hat Enterprise Linux v7.3,  
and I’m accessing the Linux server using GO-Global for UNIX.

`glxgears` runs, but lags heavily.  
Also, when I close the glxgears window,  
I get the following error:

```auto
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server "XXX:X"
      after 181224 requests (130085 known processed) with 0 events remaining.

```

ParaView 4.4.0 64-bit installed on the same server runs normally.

Any help is appreciated. Thanks!!

Setting the `QT_X11_NO_MITSHM=1` environment variable setting should help.

Thank you for your suggestion!
