Created attachment 174806 [details] Screenshot of kioworker consumption SUMMARY When opening a large (>~2000 lines) text/source file in Kate, kioworker process start consuming unbounded amounts of RAM (Whole 24GiB on my system), the system then falls into swap (zram) and slows down, until eventual OOM or I kill kioworker manually. It might immediately restart and repeat the same behavior, forcing me to kill the kioworker process multiple times to bring my system into a usable state. STEPS TO REPRODUCE 1. Open a big enough text file in Kate, like /var/log/Xorg.0.log 2. Wait a bit OBSERVED RESULT System comes down to a crawl, need to kill kioworker. It is possible that some of my system configs are causing this. I have previously updated from Plasma 5, and it was notoriously present forever after. However, I believe that if my configs are causing this it still should be fixed as it could indicate incorrect handling somewhere. I am not sure what config files to upload yet, so please request them individually after reviewing the issue.
