I switched to Wayland by enabling modesetting (for KMS) in nvidia drivers and the scale persists after a reboot when using Wayland instead of Xorg.

Top bar, windows, and fonts are all unscaled and TINY. - I'll go to Control Centre, Devices, Displays, and see that scaling is set to 200%. - I'll then change the scaling to 100%, and hit apply and confirm. At this point, windows are scaled to 200%. - I need to change the scaling to 100% AGAIN. Now everything is 100%, and therefore tiny - I then change the scaling to 200%, hit apply and confirm, which does barely anything - I then need to set scaling to 200% AGAIN, hit apply and confirm, and only *then* everything is properly scaled. I need to do this every time I log back in.
