--- Comment #2 from Peter Ullinger <peter.ullin...@gmail.com> --- - The name of the process causing the high CPU load is thumbnail.so according to htop and ksysguard. - The process is started every time I browse a folder with Dolphin and switch on the preview. thumbnail.so will then use 100% of one CPU core until I kill it, even if this folder has only three PDFs or two videos in it and those are shown after a split of a second. - Sorry, but what is a callgrind log, and where do I find thumbnail.so's one?
