Getting this issue in Arch Linux testing with plasma 5.5. Just had to close all my apps and restart desktop, because Xorg was at 2.7G RAM usage. Xorg is the main issue, as it's memory usage raises faster than that of plasma. Plasma 5.4 didn't show this problem. 5.4.95 did, and issue is still present in 5.5 final.
