mouse became a square box using Html5 user portal

Hi everyone,

we are facing an old problem trying to connect with the user portal to a windows 11 workstation.

We solved in the past, using this way (that still works with w10 pc):

**********************************

gpedit.msc (esegui come amministratore)

configurazione computer ->
modelli amministrativi ->
componenti di windows ->
servizi desktop remoto ->
host sessione di desktop remoto ->
ambiente sessione remota ->
utilizza il driver del display grafico WDDM per le conessioni desktop remoto = disabilitato
***********************************

but this way seems to be not enough for the new w11.

Anoyone can help us ?

thanks in advance,

Paolo Perugini
