Nvidia driver messages

When running basically *any* app (for example, Wine's notepad.exe), I am
receiving a log spam in Xorg.0.log from the Nvidia driver (see attachment; the
messages repeat endlessly).

This happens in various situations and most reliably when moving the mouse
cursor in the menu bar area (the messages repeat for *every single pixel*
moved).

I've researched about these messages and it seems the Nvidia driver issues
those messages whenever an X client probes for available devices using eg.

It could be a problem with the driver, but since this issue only happens with
Wine, I believe Wine could be at fault. Besides the log flood, Wine completely
hogs the X server when running on dual monitors (presumably due to the repeated
device probes), so it is impossible to run Wine with an external monitor
connected via HDMI in this scenario.

Running on ArchLinux (x86_64), kernel 5.14.12.

Video card: NVIDIA Corporation GM107GLM [Quadro M1200 Mobile] (rev a2)
Driver version: 470.74-8

Wine version 6.16, but also occurs on compiled Wine from Git.
