In the screenshot below, you'll see that one of my processes is using 139GB of memory, but htop reports the system using 6GB of RAM.
It's because htop hides mmap(MAP_SHARED) memory. This has caused a great deal of confusion in the machine learning community over the past year. For example https://twitter.com/JustineTunney/status/1778420352504512774 one Twitter user got snagged by poor performance because his system was swapping, but according to htop everything was fine.
Could htop start reporting this information? Thanks!

Hi, I might experience the same issue with htop version 3.3.0-2 on ArchLinux where the swap memory usage statistics of htop differs from those shown by top and /proc/meminfo. Please find the following screenshot for more detailed information. I tested Line 213-215 in linux/LinuxMachine.c and found these variables match with the correct memory consumption listed in meminfo. I suppose these variables were incorrectly changed during the whole htop workflow although I have not investigated the root cause in depth.
