Status in linux package in Ubuntu: Confirmed Bug description: In eoan on a 5.3 kernel, have noticed a few incidents of the system becoming sluggish/unresponsive, which appears to be caused by low available memory. top is reporting 13 of 16G are "used", but adding up the memory reported by top sorted by memory usage appears like it should be closer to 3-4G "used". Attaching two top screenshots, one shows 3.3G used and system behaving well, the other shows 14G used and system lagging. In both cases, approximately the same programs are being run taking up approximately the same amount of resident memory, so not sure where all the memory usage is coming from.
