Nvidia driver update causing suspend + screen tearing problems on Arch

I have a GeForce RTX 2070 SUPER, running Arch with GNOME on my computer.

I do recall having screen-tearing before the recent nvidia driver updates (specifically from 450.66-21 to 450.66-22 on Arch), but activating Full Composition Pipeline was able to fix it. However, upon updating, the screen tearing came back. Upgrading to nvidia-455 did not fix any of the screen-tearing.
Throughout this entire process Full Composition Pipeline was active, and was able to reduce some screen-tearing, but not all of it all the time.

With no kernel modesetting and no additional options to my xorg.conf besides Full Composition Pipeline, there is no screen-tearing, but there are suspend problems. I see a blank screen immediately after awakening that hangs for a second or two before the screen loads. Such a suspend problem did not occur before the above nvidia driver updates. After the screen loads, some applications (e.g. anki and vscode) have black artifacts and other graphical issues. For example, in anki, the entire screen is black while in vscode, I see some black rectangles off to the side and the text for the terminal prompt disappears. Changing workspaces gets rid of the blank anki screen while hovering over the artifacts and reopening the in-application terminal fixes vscode issues. Nevertheless, this is an extremely annoying issue that also affects some GNOME themes I tried to apply. I suspect this same issue affects other applications.

I spent up to an hour and half researching the problem on the web and trying different solutions, but to no avail.

Modesetting (e.g. nvidia-drm.modeset=1) without TripleBuffering and IndirectGLXProtocol options in xorg.conf results in no suspend problems, but significant screen-tearing

Turning TripleBuffering on and/or turning IndirectGLXProtocol off results in the above suspend problems but no screen-tearing (with and without kernel modesetting).

As you can see, I am either left with having screen-tearing but no suspend problems or no screen-tearing and suspend problems.
Downgrading just the nvidia packages to a version before the driver update that broke my setup breaks lightdm.
Downgrading to a mirror on September 17 (before the driver update) is doable, but not ideal as I would rather have software updates with graphical inconveniences than a computer stuck in time.

I am not entirely sure this is an issue with the nvidia driver specifically, but given the above events, I believe it is quite plausible.

Please tell me if you are experiencing the same issues. I would like to know what solutions you have tried as well.
