It looks the most suspicious. And what "if > needed" does mean? I have no idea why need to SWAP, perhaps it is better to ask the original author :) https://github.com/KDE/k3b/commit/97f72a28ef87ef62f89967e237f441e03d3b5b3b#diff-edc47aa8fac740c80253cd4bec4ba15dR207 You can test to comment the SWAP code, then rebuild K3B to verify whether or not produce the noise.
