Hi, thanks for the report. Could it be due to SSBO support for this platform is removed?: https://wiki.blender.org/wiki/Reference/Release_Notes/4.0/Core#Minimum_Requirement_changes

@Jeroen-Bakker , can you check?

This has to do with an issue in workbench where it the the fallback for shader draw parameters is broken. Is something we are looking into so fine to confirm this issue for now. Is also reproducable when starting blender with --debug-gpu-force-workarounds
