Hey Sam,
Yeah, I’ve tried it on Edge, Brave and Chrome. All do the same thing. HDR isn’t supported on my monitor, so it was already disabled. Drivers are running stable, and I’ve run the latest package. The display resolution was running at 59.98 Hz, which I changed to 60Hz but that hasn’t changed the behavior.
An odd duck this one. I’ll try a few more things with the hardware setup. Maybe find a different monitor and see what happens.
