mac m1 screen saver bug: has it been fixed ?

The 'screensaver takeover' bug affecting macos on M1 processor has been reported for a while, forcing users to deactivate fast user switching.

Has this bug been fixed by macos 11.3 ?

Deactivating fast user switching is definitely not an acceptable solution for anyone using a mac mini as a family shared desktop. Anyone aware of a different workaround that would not involved killing fast user switching ?

The lack of fix after 4 months for a bug that has been widely reported is concerning. Could it be that Apple could not find a way to fix it through a software patch ?

Would be great to have some feedback from imac M1 users when they become available.
