120Hz limit for high refresh rate support seems strange. The most common refresh rate for high refresh rate monitors is 144Hz, and faster refresh rates are available. If you run a 120fps animation on a 144Hz monitor you'll get duplicated frames, which negates a large part of the benefit.

My first thought was that this was done with consideration for mobile phones, since many higher-end models use 120 Hz displays, but Ladybird does not seem to support mobile for now.

But the phrasing of it about "can now" suggests to me that this may simply be a performance issue too. They changed it from 60 to 120. Perhaps in the future they can go from 120 to 144 or even 240.

I think this was just worded a bit wrong in the newsletter. In the actual code, it is set to the refresh rate of the screen itself.

Maybe the developer that implemented it only had a 120hz display to test it on?

There are monitors running 120hz and you can set most 144hz monitors to 120 if you want to down clock them

Also why would running 120 frames on 144 largely negate the benefits ? The whole reason we settled on these numbers is they are all multiples of 24 in the first place
