For users relying on features that have been introduced between 6.6 and 6.12, they cannot downgrade to 6.6 and also cannot upgrade to 6.12, leaving them without vulnerabilities being patched on mainline and LTS.

Per my comments on the bug report, did you also update mesa or GPU
firmware?  If so, can you narrow down if any of those other components
had an impact?  Alternatively, can you bisect the kernel?  If you have
known good and bad kernels, it would be really helpful if you could
bisect to identify what commit caused the regression for you.
