Qubes OS 4.3 should be released soon, an interesting #privacy feature is cloaking user input patterns :goose_peek:

> Add event buffering for cloaking user input patterns
The user may wish to prevent biometric information about their mouse
and keyboard patterns from leaking into certain Qubes. To make this
possible, this feature inserts random noise into the delivery timing of
all X events, making it more difficult to distinguish the user from
other X event buffering users. The maximum delay in event delivery is
user-configurable through the "events_max_delay" configuration option.
