this is what i mean

hi im new to fedora i came from ubuntu anddabian and thought to try out fedora kde plasma 36 after i updated and upgraded to kde plasma 5.26 my system monitor started displaying ram usage at 2.5GB While i only had one app open like stremio tostream a series and when i installed htop it showed differently from system monitor htop displayed ram usage at 1.6GB which made the swap memory be used more leading to the point of apps freezing and crashing it very weird to me. its there a reason why system monitor displays differently from what htop displays?

Which column are you looking at in htop?

One main reason for a discrepancy here, is that System Monitor uses a slightly different value than most tools. This is referred to as "proportional set size", PSS. Which is a process' private memory amount, but with a proportional share of the shared memory added. This results in more memory used reported, but the value is actually more correct.
