● If you change the mouse pointer size to a number greater than 3 in a Blast session, you must use Ctrl+Alt to exit the session
and view the floating bar on the ThinOS modern desktop.
● Camera redirection support is limited. A blank screen is displayed. This issue is due to VMware Horizon limitation.
● USB disk mapping is not supported by VMware Horizon on ThinOS 9.1.
● Video performance is poor since Multimedia redirection (MMR) is not supported on ThinOS 9.1.
● Limitations for VMware Horizon in Wyse Management Suite or Admin Policy Tool:
○ If you change any Horizon-related configuration, you must sign off from the broker and sign in again for the changes to
be applied.
○ Set the force redirect setting for Horizon from Broker settings > VMware Broker Settings Include Vid/Pid
