Monitor's OSD

SUMMARY

After disabling Adaptive Sync in settings my G-Sync monitor still behaves as if it still is in G-Sync mode.


STEPS TO REPRODUCE
1. Disable Adaptive Sync
2. Check monitor's OSD

OBSERVED RESULT

G-Sync is not disabled.

EXPECTED RESULT

Monitor is in "Normal mode".

Kernel version: 6.6.8-arch1-1

ADDITIONAL INFORMATION
It's an ASUS PG27AQN. It has a feature called ULMB2 and in order to use it I need to disable G-Sync, but I can't. I'm attaching a photo of monitor's OSD. I have tried asking on KDE Discuss and Reddit, but there was either no answer or suggestion to post a bug report in the latter.

Okay, KWin is properly turning vrr off. The problem is on the driver side, so please report this to NVidia
