After testing Debian SID + Cinnamon, I confirm that the bug seems resolved for Debian 14. The NV 5000 series GPUs are now natively supported under SID. For the NV GPU series 1650 and higher, it is now theoretically the "NOVA" GPU driver that has taken over from the old "Nouveau" driver. On the other hand, the bug persists in Debian 13, it will certainly not be resolved... Regards.
