HDR font rendering

KDE 6.2.3 Nvidia 565.57.0.1

When I enable HDR, my fonts are atrocious. I found this reddit post with the same problem, with the same monitor.

If I turn off HDR, the fonts are fine. If I set scaling to 125% fonts are fine. If I take a screenshot, the fonts are fine, so it feels like it might be visual on the monitor itself? I tried to take a screenshot using spectacle to show it, but it looks fairly normal.

It’s really bad and 1125% is unusable as it is too big for me and it causes buttons and UI elements to be messed up.

I’m not sure what to do, I didn’t see this problem under Windows and I really want to keep HDR on and not have to toggle it on and off when I launch specific games.
