There is nothing we can do about it.
Quoting from the README in the package:

NOTES ABOUT REPORTING BUGS TO NVIDIA

The NVIDIA graphics driver is a non-free closed-source product. Therefore
the package maintainers are limited to fixing bugs in the packaging.
Bugs in the "graphics functionality" like graphical distortions,
performance regressions, hardware support, ... can only be fixed upstream
and should be reported directly to NVIDIA because this includes collecting
system information (with the nvidia-bug-report.sh script that is included
in the nvidia-driver package) on the affected system.
NVIDIA's bug reporting instructions can be found here:

https://devtalk.nvidia.com/default/topic/522835/linux/if-you-have-a-problem-please-read-this-first/
You may additionally report the problem in the distribution's bug tracker,
but please include a link the related thread(s) in the NVIDIA forum.
