ZZ9000 problem after firmware update to 1.9.1

Hi,

after upgrading my A4000 system to:
• AmigaOs 3.2 from 3.1.4
• newest picasso96 drivers to version 3.1.2 (September 2021)
• newest ZZ9000 firmware v 1.9.1 and v 1.9 drivers

some demos for example: Starstruck from TBL, Singularites from HJB, didn’t shows on monitor anymore (black screen) but the demo running (music playing etc). Some demos running ok, I think is 50/50.

AmigaOS works perfect.

Before the upgrades everything works OK.

Any ideas?
