I'll have to go through with some of the same steps to see if a recent problem I had is related to this. In my case it was actually being triggered by a piece of monitor management software that came with the LG ultrawide monitor that I use. No significant CPU load, no memory issues, plenty of cores in an older HP workstation with a Xeon Processor, 48 gig of RAM and a Samsung SSD. When that display management software was running a text editor couldn't even keep up with displaying text as it was typed. Edit: rereading some of the original 2 articles, yeah, I'm not going to be running the same kinds of tests - even if I did it'd take too long to develop the knowledge base to be able to interpret my results adequately.
