Polish: Slight innacuracy in the memory display?

[Ray-Escobar]

This is just a minor visual "bug". I believe the memory meter should display in way that is more aligned with actually memory used? i.e. here I am using around 30% of the available memory, yet the meter is way above 50%. Not sure if it's intended that way, but could be a small visual improvement. This is from htop version 3.3.0 installed via apt.

This is intentional and the yellow/orange part of the meter is memory that can readily be freed up when needed (e.g. filesystem caches). And if you look at the display itself, it reflects the actual usage to be about one third (10G of ~31G).

What might be a bit confusing at first is, that the cache portion is drawn in, but this is actual memory being used, thus not drawing it, would be wrong for different reasons.

The current way things are handled is a bit of a compromise: It shows what memory is used and for what, while also providing an indication how much is free to use. If you ignore the orange part (which is intentionally drawn last), you end up with the 10G of actually used memory that isn't easy for the OS to free without much additional work.

I hope this explanation helps the decisions made when this visual was implemented.
